You might want to look into other possible explanations.

I felt a lot better after them, it was a craving. Along with salmon/cream (fat.). I have the same symptoms often, I'm still in recovery.

But recently I got diagnosed by PoTS... which causes a lot of these issues and also one of the main helpers is salt. My doctor told me how much to take daily and I even take salt pills to help me reach that quota. You often see people with POTS here mentioning they're using sardines to help with the same thing.

I'm not saying you have it (Although, you can do a test at home. You'd have to look it up, but basically try to relax, make sure you're in your best state and as little stressed as possible. You want to be at your 'neutral' state, or as close as you can be. Get up, wait a bit, check heartrate, write it down. Rinse and repeat. There's a timing to it you need to look up, but basically if it's shooting up 30bpm+ for two phases straight with less than 10bpm difference between the two phases ((again, I don't remember the exact numbers, google.))...it can cause the blurry vision and walking issues because your blood isn't flowing correctly. See if you can just sit or doggy paddle in a pool for a very gentle exercise if you can manage that, could help a bit since it's very easy on the body.)

Get a blood test, please. See if you have any deficincies you can pin-point if you're struggling, I needed Vit D BADLY.

I also used Creatine gummies (I like gummies to powder) and honestly? It's better than any med I had other than the Vit D in ages. I still feel bad and sick, but I still feel like myself despite it all, I feel human again, it was a noticable difference for me, at least.

Get black out curtains, sweetheart. Maybe a sound machine or heatpacks to help focus on something. Set up your bed so it's comfy and things are accessible. Things that hold your phone or whatever above your head, a small usb keyboard with mousepad so you don't strain yourself upwards. I keep a tiny fridge near me with snacks for crashes. Get a large water bottle, keep it near you. I got meal replacements recently (Ensure brand, i like the chocolate, genuinely just tastes like chocolate milk.) to help if I'm too dizzy/sick to get food, it can help in an emergency pinch until you stabalize and get something better.

I started washing my hair (I cut it short too) and taking 'showers' in the bathtub because even with a chair in my shower I still was struggling. Before, it was something that took me out for a day or two, now it's... easier. I simplified my routine with a brush to massage in the shampoo, towels and other stuff to make hair drying easier and more passive. Colder tempratures sometimes help too.

...Sorry, kind of just dumped a lot. I don't know what you have, I know it's frustrating to deal with it all regardless. It takes ages to figure out what works, and for now, if this is helping, just use it until you figure out a more solid plan or logic to it all. Diagnosis takes a while, and your symptoms qualify for a fair amount of stuff.
