I swear you are on to something. I have been on them for 9 years, and I am basically fried and useless. It's as if I had never been treated at all, if not worse than that. I feel like I am in a constant state of burnout, without actually being burned out, so to speak.
I mean ADHD medication is essentially meth. At first it works, and then you need a little bit more to get the same effect.
I was diagnosed with ADHD at 19 years of age (quite a while ago) and it took me 9 months to realize the medication was a net-negative for me.
I encourage you to seek other forms of treatment that aren't medication-based. What works for me is a lot of exercise, good sleep, healthy diet and limiting "easy" dopaminergic activities like scrolling random content or watching random YouTube videos.
Good luck.
The parent comment mentioned feeling tired after consuming something with a lot of sugar, was that really a mystery prior to using CGM? I doubt it.
Sure it's interesting to correlate to your perceived wellness (or lack thereof) with a wearable spitting out data but after the novelty of this discovery wears off my guess is that people will simply stop caring to check what they already know to be the case.
