I survived pre-diagnosis by heavy amounts of caffeine (which never did much for me) and judicious journalling, externalising thoughts does totally work for some people and at the least you’ll have a reference as to what you’re doing to come back to. I keep up the habit even on meds, helps on the days I accidentally forget a pill or late calling in a renewal (it’s really irritating I have to call every 60 days BTW, no refills for stims apparently)
I’ve used the wired equivalent of the Logitech g502 for a while, and my partner has the wireless one, I liked them as well. I’ve used Logitech, steel series, Razer and Saitek mice over the years, started with a Logitech G7, and there’s a reason I went back to Logitech mice after using some of the others. Imo you can’t really go wrong with one of their midrange models with a decent sensor, won’t break the bank and found them fairly reliable.
As a bit of an alternate, I know you prefer wireless, but I’ve been using a Ploopy Mouse for few months now. I don’t do online fps stuff anymore, but was great for FPSs (some boomer shooters mainly) and RPGs it’s solid, been playing a lot of Diablo 2 recently and it’s great. It runs qmk so it’s customisable however you want, sensor seems decent and the entire thing is open source, designed for user serviceability.
