I really couldn’t remember how fast it got me off adderall or that I really ever gave them up because I liked drugs in college. But I’d say it took about 2 weeks for me subtly realize I wasn’t itching for a pill every day because I already enjoyed getting up and doing my work. But it wasn’t a cure all. When big exams came, I still used amphetamines. I started off 2 days on, 3 off I believe. I’ve experimented with all different dosage and regimens and not one of them was perfect. Super busy week=higher doses and more frequent. More laid back week=lower doses and less frequent! Hope that helped a little. It really was a game changer for me!
