While my hypomanic episodes are thankfully pretty infrequent, I find that adderall and welbutrin usually exacerbates them. First thing I usually do when I feel like I am in or about to experience an episode is tell my parents to keep most of my money so I don't spend it all on stupid crap. While i've tried drugs like lithium, I usually stop taking it after a few days because I want to feel good.

Honestly, what helped me was finding a cheap and creative outlet for all that energy whether it's writing a paper, playing open-world videogames, trying to learn a new skill, etc. Something to make me feel productive I guess. I usually end up going overboard or half-doing a ton of things, but it still helps I guess.
