Consistency over quantity has worked well for me. Getting outside early, as close to when you wake up as possible, and going for a walk is a good way to build up to jogging. 15-30 min of cardio does a lot for cognition, doesn’t have to be intense either.
I regularly exercise on 10-15mg of adderall, and while I definitely sweat more and my HR is higher, I’ve never felt like the meds have made it dangerous to workout for my heart.
Which meds?
When I started taking adderall at about your age I felt similar so I tried to make sure I was covering all of my bases-exercise, sleep, diet, supplements, organization.
I’d suggest trying to stick to some new, productive, habits for the first 3-6 months. That will go a long way and set you up to be able to do less or get off over time, ime. Learn healthy habits with medication, easier to do them off the meds.
Good luck!
Overthinking? With adhd??! Lol, I get that. Glad it helps! Nice with the small community here, seems more genuine.
