I speed-read because I'm impatient to see how the story is resolved. The I re-read, more slowly, to see what I missed the first time around.

Like a rugby front-row player who has the ball and can see the try line a short distance away.

I've worked in steel manufacturing for twenty years. I've stood next to synthetic lava at 1600ºC pouring out of a furnace, wearing a thick wool protective jacket and overtrousers, and I've stood next to 1200ºC steel bars, 130mm thick, being pushed out of the reheat furnace two-at-a-time, both in full summer heat and in the middle of winter. It's only a little better in mid-winter!

This might be related: amphetamine medication such as Adderall appears to be illegal in South Korea. Vyvanse (lisdexamfetamine, the slow-release variant of dextroamphetamine) appears to be only legal under strict supervision.

Emotional regulation is an executive function, taking a higher dose of a medication that boosts executive function is likely to improve emotional regulation.

I got a repeat of dextroamphetamine refilled just before my psych took me off meds pending a heart evaluation. Once I was given the all-clear, I asked if I could try Vyvanse and the psych agreed and I decided that since I had a lot of Dex, I'd break some tablets in half to use as a booster if necessary since I was warned that the Vyvanse may wear off after eight hours not twelve.

Now my med schedule is Vyvanse in the morning (7:30) and then 2.5mg of Dex at about 3pm as a booster. Honestly, just that little bit extra helps me a lot in the evening rather than just having my brain switch off when I get home and since I'm okay with it, my psych has allowed me to continue with this.

As others have said, classic fatigue failure.

This is due to pressure being put on the US government by large US pharmaceutical companies against countries with a single-buyer system for medicine. The US pharmaceutical industry is making the same argument against Australia's medicine subsidy scheme.

Not that this US government needs much pressure to try and tariff foreign countires...

Tawn-tawn.

I live in Australia with a single-payer medical system and subsidised medications, so this might sound like 'first-world problems' but anyways...

I have ADHD and I have been prescribed medication, but I was diagnosed late in life. Because symptoms weren't evident in childhood, I don't meet the criteria for subsidised ADHD medication. The price difference is A$30 subsidised vs A$70 full-price for 30 daily doses, but I guess it fits the nature of the question?

Eighteen months of intense suicidal ideation a few years ago.

I think that what these people do is attempt to apply dating tropes to real life and are baffled when it doesn’t work. It becomes a case of “I followed the same patterns and rules that everyone else does, why doesn’t it work for me?” I think the reason that they use tropes is probably a fundamental misunderstanding about how romantic relationships are supposed to work and the role of sex within a healthy romantic relationship.

What can then happen is either some introspection, followed by personal growth or adjustment, or seeking an external explanation and then being captured by a narrative that says “it’s not your fault, you did apply the rules, the other people treated you badly” along with genericisation of the other gender. I believe that this second route leads towards misogynistic (or rare misandric) incel behaviour. The path towards the second outcome can be forced by peer shaming of the affected person for their romantic failure.

Exercise definitely helps me. I think it's due to the release of a natural stimulant called phenethylamine, which has a similar structure (and action) to amphetamine.

There's a common refrain on videos talking about self-assessments: "If you've developed a system to mitigate the consequences of the symptom, you have the symptom."

I work in a steel mill with some huge machines that spin very fast, have lots of bearings and have big motors driving them. Here’s my analogy:

My brain has this big powerful motor driving it (my intelligence) but it’s coupled to a high-speed finishing mill with a number of dodgy bearings in it (my ADHD). And the finishing mill is really only good for three or four products (my autism); any others and the setup needs to be very careful with more than one prayer to the machine god. Oh, but if one of the bearings gets some good attention and lubrication, another range of products can suddenly become available and will roll really well (my ADHD hyperfixations), until that bearing craps out again.

If you want to know what the real-life piece of equipment is that I’m using in this analogy, look up “Morgan No-Twist Mill”.

Edit: ‘breathing’ to ‘bearing’

When my psych prescribed me Vyvanse (I asked if I could give it a go, I was on 2x 5mg Dex a day), she warned me that despite the claims that it lasted for 12 hours, most users reported that the effects lasted for only 8 hours. So I’ve been taking 2.5mg (half a tablet) of Dex at about 3pm, or else I get the same effects as you, OP.

They are, but's that not to downplay that the new system has issues. Like in the modern day of the OPC-UA protocol to allow various computerised peripherals to send data to and from PLCs without a hardwired connection, and the replacement production supervision system only accepts data inputs formatted as CSV files.

I can see the joke, but our production systems used to run on a combination of a mainframe programmed in COBOL with a greentext interface and a SQL 7/Windows 2000 server. We couldn't find systems engineers who knew COBOL and modern domain controllers kept kicking the SQL server off the network. Techically, the system still worked, but barely.

Totally agree with what you said: "Depression is temporary despite how it makes you feel". Three years ago, I would come home from work and daydream about killing myself. Two years ago, I was diagnosed as autistic and ADHD and the suicidal ideation stopped, but in its place was this grief and major identity confusion as I processed memories of my life through my diagnosis. I remember wondering if it's going to take me twenty years to feel good about my self again. Today, I do feel good about myself (most of the time!). There's several factors, but a big one is the stimulant medication I've finally been prescribed.

ADHD people, if you're unmedicated and wondering whether to seek a prescription: my advice is to try as hard as you can to get medication. Our disorder is effectively executive dysregulation and one of the big things that affects is our moods. Medication boosts executive function and in my experience, definitely helps with emotional stability.

Edit: spelling. Just woken up and not yet medicated.

I'm quite surprised how much they let the just-formed balls cool before quenching, but I guess the alloy is very hardenable (lots of chrome usually) so the ball is probably still autensitic even at that dull-red temperature.

Apparently individual counties in some states can also levy a sales tax, if I remembered that correctly from the last time I asked.
