AFAIK some neurodivergent brains deal with amphetamines differently and the baseline levels of chemical affected by amphetamines is different.
Wear and tear might be a thing, i don't know, but the analogy of putting NO2 in their car feels a bit off.
It'd be more like finally putting premium unleaded in your car after years of "back of the lorry" pseudo-unleaded.
You're right that, for people with ADHD and related disorders, stimulant medication sort of just adjusts their baselines so they can pay attention like a "normal" person.
I have ADHD and take metylphenidate(I've tried many kinds of stimulants as well) -- and the NO2 analogy is an imperfect but better analogy than saying stimulants simply adjusts the baseline of people with ADHD to function like "normal" persons.
I feel there is a narrow window of dosage and time where it might feel that way -- i.e. stimulants at the onset might calm you down, reduce anxiety, but all stimulants are very broad hammers.
For me it feels like it's impossible to re-create chemically exactly the neurotypical focus that I've seen in other colleagues.
Like spending 5-6 hours of continous work where you drill down just enough, get back on track, don't get distracted, don't get too anxious, don't get hyperfocused AND do that consistently, day after day after day.
My non-chemical modes are either hyper focus for 2 weeks on a problem, immerse myself but then completely lose interest, most of the time without showing much for it OR procastinate it a long way, get extremely anxious and work really hard on the problem.
With stimulants it's a bit like: - dosed just right:it evaporates anxiety, stressful situations feel easy to deal with, BUT there's always increased heart rate, grinding teeth and some tension at the end of the day - some stimulants make mundane things wildly interesting (on isopropylphenidate I spent a few hours playing with a PLSQL debugger because I thought it was really cool), but no sense of "GO, GO, GO, do it". - some make things seem urgent enough and help stay on track -- like the metylphenidate I'm prescribed. - some make going into a flow-like state easy and fun (like methamphetamine and phenmetrazine). - some are pure energy and urgency -- like modafinil.
All of the stimulants have the potential to give me euphoria, all of them temporarily increase libido I still have to be mindful of not focusing on the wrong thing, the "normal" feeling is very fleeting, it's very easy to get hyper on stimulants, all of them feel like wear & tear at the end of the day, some more than others.
I wonder if you tried lisdexamfetamine? I can't get it prescribed easily here since it's not covered the way the alternatives are but someone i know had amazing success with it. Seemingly because it's a prodrug. I can't help but be hopefull that I'll get to try it one day and that it ends up being what I always needed.
It's not legal where I live also, I did try 2-FMA and it felt better in certain scenarios -- like following a hard course, but I also felt the tolerance ramps up much faster in releasers than re-uptake inhibitors so methylphenidate still is a wonderful tool.
Once I got prescribed lisdexamphetamine, my life turned around almost instantaneously. While it doesn‘t really get rid of my ADHD, it does help tremendously. The everlasting brainfog isn‘t as debilitating anymore. When I get excited about something I actually tend to follow through. I still battle with my obsessive tendencies — like getting stuck at setting up the perfect project tooling stack or spending way too much time on planning and research instead of just getting to work — but these are not so much related to ADHD.
On lisdexamphetamine, I am more social, my appetite is better, when I actually commit to something, I tend to stick to it for much longer, and I have also picked up a bunch of healthy habits. For example I exercise almost every day now.
If you someday get a chance to switch to lisdex, do it. It’s much smoother, longer-lasting, with fewer side effects. But honestly, anything is better than ritalin in my book.
