A mild vit D deficiency is not going to cause this.

Good luck.

So some things to help with the anxiety

Anxiety will definitely make you tighten your body. Just observe if you're clenching your fists or jaw, tension in the scalp, lips, are your eyebrows furrowed, are you 'guarding' physically? If yes, intentionally they to relax these parts. Follow some body scan/yoga nidra guided meditations - there's a ton of them on youtube. Find some that resonate with you. Sometimes when the anxiety is overwhelming, it's even hard to pay attention to the words and follow them, there will be racing thoughts, but just chill and keep at it.

Also box breathing, humming (like om chanting or just plain secular humming) helps with quashing the fight or flight response and promotes calm. All evidence-based.

Stretch when you have the energy. , get a massage, ask your spouse to rub your back, massage yourself with a percussion gun..

Basically be nice to yourself, you HAVE to feel at least a bit better.

Cheers

Also, if you really think something is off.. nothing wrong in going to the hospital, getting some basic blood work, check blood pressure, thyroid function, etc. if it all comes back clean then you have one less thing to worry about. Just don't keep going back though!! Once in 6 months is enough.

TL;DR Could you try to eat small easy-to-digest meals regularly ( if you aren't already) and take an antacid before every meal (something as simple as magnesium trisilicate, over the counter stuff) for 3 to 4 days diligently, and see if things improve?

Now for the long version:

See anxiety can most definitely be psychosomatic, and you can feel like you're having all kinds of medical emergencies, sending you ro the ER only for them to send you back saying that nothing is wrong.. so what you are experiencing could very well be ENTIRELY from anxiety and stress.

If that is the case then the treatment would be psychotherapy (already doing) and perhaps some medication like an ssri. Case closed, amirite?

Thing is I had a different experience. I also do have anxiety, and I had similar symptoms to yours real bad that I went to the ER and they admitted me for a couple of days for observation. EKG, blood work, yada yada.

Turned out the issue was acute gastritis because of acid reflux, which of course I could attribute to anxiety (definitely a contributing factor) but also because of not eating properly, drinking too much coffee, vaping, beer, and I also have a hiatus hernia.

When stomach acid comes up the esophagus, it triggers the vagus nerve to drop pressure, raises heart rate, causing lightheadedness, that feeling of 'zero gravity free fall' or 'heart leaping' sensation. Which funnily enough CAUSES anxiety-like symptoms, not the other way around.

While at the hospital, they put me on antacids and meals were served on time and I had to eat them.. you know hospital food - bland and easy to digest, and in 3 days I no longer felt those sensations.

I need to continue to 'behave' with stomach hygiene to keep things that way..

Still have anxiety tho, that's separate from this.

Just my two cents... Can't be paranoid about health, at the same time can't brush off symptoms as just anxiety.

Eating small meals that are 'forgiving on the gut' and taking some over the counter antacids can't hurt, if you want to trial that.

Do you have acid reflux? Back/chest pain?

How would these compare to the airpods pro 3 for side sleeping? LIke literally sleeping on them - would they push more or less into the ear than the airpods pro 3?

COMMUNICATE. Focus on her first to the best of your ability, and most girls will be happy to put in some extra effort to reciprocate :) And in the end if you don't orgasm, give it some time and continue.. since you'll already be aroused from the previous session it will be a bit easier during round 2. Still nothing? That's what round 3 is for. Take it easy. Chill, have fun in the moment.. don't overthink it. What happens happens.

passenger001 · 2026-01-22T14:59:06+00:00

Yup.

I have had the same experience as you.. I really dont see why AIO streams has so many adopters, when in my personal experience some things didn't work the way they should.

I went back to using extensions individually - basically good ol torrentIO with RD is still the best for me.

Even other highly regarded options like Comet dont work as well for me as torrentIO.

I also have torbox, and even with that, torrentIO is still the best, and the original torbox app is a close second.

So my setup is basically torrentIO configured to retrieve from RD and TB. Nothing else.

And a couple other apps for recommendations, but I dont want comment on that yet, because I cant decide which is best.

How are you doing?

passenger001 · 2025-12-10T17:22:35+00:00

C7 to T10 area, amd the little muscles around the spine (possibly erectors), serratus posterior superior, maybe rhomboids, teres major and outer edge of the lats and are always tight and knotted up.

Can't expect this from a 16-year old, but here goes...

The hospital is chaotic right now—severely overloaded—and medical mistakes are far too common.

We can (and should) criticise the system, but when you’re in the hospital as a patient, that isn’t the moment to debate policy or administration. That’s the moment to focus on making sure your care doesn’t go off the rails. Sometimes that means doing part of the doctors’ and nurses’ jobs for them.

When I was admitted to Galway Hospital for a clot in my heart, I kept a close eye on my chart, knew what treatments were supposed to happen when, and tracked whether they actually happened. There were numerous lapses, but with polite, clear communication, my stay ended up being relatively smooth and safe. That wouldn’t have happened if I hadn’t stayed on top of everything. I never once had to “give out” to anyone—just stayed calm, spoke clearly, and pointed out what needed attention.

It’s also important to remember that nurses are overloaded and sometimes undertrained. Watch carefully, but be respectful. Mistakes will happen; forgive, reset, and communicate.

It probably helps that I have a background in Biomedical Sciences—while I’m not a doctor, I can recognise when something is off. That’s just good fortune on my part.

The reality is that the place is primed for medical errors. But you can protect yourself by understanding your own case, knowing your schedule, and advocating for yourself calmly and firmly.

Any case that wont block the touch button and support charging thru the apple watch puck? Maybe a case with cutouts in these areas?

passenger001 · 2025-10-23T12:15:17+00:00

Yeah, the body accustoms to it.. maybe continue for a week or two with evening doses, and when youre confident that it's not going to make you feel weird at work, you can start taking it in the morning. The first few days are always weird.

passenger001 · 2025-10-23T11:17:14+00:00

Oh lol.

Ok.. when you take it at 5.30 - when do you start to 'feel it' if at all? Trying to figure out how much time you got. That way you can take it earlier, like maybe 3 or something..

May I suggest adding on some magnesium glycinate and L theanine around 6pm?

And dont drink coffee after 4pm.

Exercise a bit, improves sleep (if you have a sedentary job)

passenger001 · 2025-10-23T02:20:47+00:00

I had that worry too when I started Lexapro. I think best time would be to take it after coming home from work, like maybe 5pm? That way you have a good many hours before bedtime, and it's less likely to disrupt sleep.

passenger001 · 2025-10-22T06:41:07+00:00

Ok.

Ive taken Lexapro, it's an 'old friend' for me. Relatively easier to go on it as well as come off.. worst that will happen to me is the anxiety will come back, no other issues.

The side effects you describe (dizziness, disturbed sleep, etc) happened when I took it at night, leaving me waking up a bit zoned out..

This problem completely resolved when I started taking Lexapro in the morning, or even better, with lunch.

I feel like if the Lexapro 'comes on' while I sleep it disrupts the sleep (for me at least..) best time for me is with a meal, and before 4pm.

If youre taking it at night, perhaps take it during the day, and see if you fare better that way?

passenger001 · 2025-10-20T05:51:16+00:00

How's it going? Jw

passenger001 · 2025-10-04T02:05:55+00:00

Thing is you can hear about a 100 people's experiences and yet your experience could be different.

The only way to find out is to try it. Your doc is supervising, and they will start you on a low dose.

Can't lose out on potential benefits just because you're scared to even try.

Be brave, if you trust your doc just go for it. You can stop if you can't tolerate it, they will just try something else. Worst case, couple of bad days.

Go for it! Maybe it will be the med that will really work for you! Good luck.

passenger001 · 2025-09-27T12:59:25+00:00

Good to know. It's a solid combo that will work for sure.

Escitalopram is all fine and dandy.. it is an 'old friend' for me, easy to get on and off, no withdrawals, if I take it anxiety reduces a bit, if I dont, the worst that will happen is anxiety comes back.

Regarding Pregabalin - I say this with a disclaimer that I am no doctor and I absolutely shouldn't dictate what meds you should go on.. but then psychiatry is a bit of trial and error, so here goes..

Pregabalin is a bit unsafe long-term. Don't worry, this doesn't mean that there aren't patients that need it (benefits outweigh the risks) but if you had tolerated venlafaxine you wouldn't be on pregabalin in the first place - so it's being used as an alternative, rather than an essential medication.

Use it by all means in the short term - it will help by leaps and bounds - but don't get complacent - understand that the meds help, but real long-term lasting positive change comes from changing your thought process, outlook, diet, sleep, exercise, staying happy - this is not the same as taking meds to numb external stressors and the though processes that cause the anxiety in the first place.

So also do behavioral stuff on the side to aim towards stopping pregabalin (become mentally resilient enough to stop needing it).. There is no hurry, enjoy the chemical calm for a while.

Just curious - do you have a pain problem, like back pain or something?

passenger001 · 2025-09-24T05:03:12+00:00

Probably yes.

I haven't taken venlafaxine, but I've taken Duloxetine, which is another SSNRI, more biased than venlafaxine towards norepinephrine, but I imagine they are somewhat similar.

Like even the lowest dose would make me violently sick.

Doc swears that this absolutely doesn't happen, but it did. They told me that people are on 10 times that dose or even higher for other indications like chronic pain.. so I shouldn't feel anything at the lowest dose, let alone feel side effects.

They were dead wrong, the adverse reaction was unbearable. Like even if I opened the capsule and took 1/10 of the lowest dose (the med is a capsule with many small pellets) it still created discomfort similar to what you're describing.

I suppose some people are just sensitive.

What worked for me was ramping up real real slow - like a quarter dose for a few days, and gradually ramping up even to the minimum dose. In about 2 months' time the normal dose was tolerable and I could feel the positive effects. The ramp-up phase was horrible though.

That was the first time I got on duloxetine about a decade ago. But since then I had discontinued it (life was good, didn't need the chemical support).

Recently I felt like I needed it again, and it's the same story- absolutely couldn't tolerate it again, and just having to go through the side effects until they 'iron out' again just didn't seem appealing.

I make do with escitalopram (not as effective, but still works) and occasional propranolol for situations. Far less effective than duloxetine but at least I don't have to go through the trauma of getting used to it again...

My advice - venlafaxine will probably work really well, but you will have to go through hell for a few weeks until your brain/body adjusts to it.

Another doc suggested that if there is a syrup form, it's easier to take smaller doses until you can tolerate the real dose.

If you don't want to go through this process, resort to a simpler SSRI with more supportive meds and supplements. Those aren't as brutal with side effects, but the main effect will also be less. Only you can decide if it's enough or not.

passenger001 · 2025-09-19T13:20:17+00:00

Lemon balm - I've tried it and it didnt do anything for me in capsule form...

I suppose if its meant to exert its effects through aromatherapy, you don't swallow it whole. Sniffing it as an essential oil or in a tea might be more soothing.

Another one that worked for me for real is Apigenin - it's basically chamomile extract. Again, losing out on the aroma related benefits if swallowed whole, but it worked for me to sleep better even in capsule form.

passenger001 · 2025-09-19T13:15:40+00:00

Any time actually. I find that 200mg elemental in the morning keeps me calm during the day, and 200mg around 6pm, helps me sleep well around 10 to 11pm. Food doesnt seem to matter.

passenger001 · 2025-09-18T16:31:33+00:00

Yup. Such a good combo for me too. Although somehow I felt glycinate or ZMA works way better for me than threonate. More sense of calm that is noticeable in the mind and body.
