For those unmedicated, how do you manage?

Adderall 2 days in a row now makes me paranoid, and I've never really been able to get a doc to prescribe vyvance or anything else, and frankly at this point, I'm afraid to do stimulants. Strattera made me feel weird.

Has meditation helped? cutting sugar, more exercise? keto? nofap? I'm really battling trying to focus on one task, then realizing I want to do 100 other tasks, so I start the research into all of them, thinking I'll do them all, one at a time, and 1000 browser tabs later (not an exaggeration 32gigs of ram can manage that), I realize I'll get none done.
