Otherwise though, it checks all the usual boxes - way easier to sit still and be quiet, way easier to do the thing I intended to do when I sat down to do it, way easier to get in and out of focus. Also improved my sleep schedule a surprising amount - between it and melatonin, I've moved from 6am-3pm to ~12am-8:30am, which is wildly outside any of the expectations I've seen set for pharmaceutical remedies, and puts me firmly in 'able to hold a normal adult job without killing yourself through sleep deprevation' territory.
Honestly almost annoying it has such a positive effect since the practical difference between that and addiction are pretty minimal on a short-term basis. I'm deeply uncomfortable with the idea of having to go without it or something filling the same brain-holes for a long period of time precisely because I'm basically worthless without it, in a way I didn't really come to appreciate until after starting medication.
