I was just like him! Btw never hit anyone, that's not a fair assumption if he doesn't yell at you or anything. But taking lithium for a while helped a fuck ton. I stopped taking it after a while and I'm still much, much better. Only downside is it makes you fat and impotent until you get off of it ngl.
I got some side effects, none were that bad except I got a lot of those hypnogogic falling sensations constantly and some balance issues. Went away within a few weeks (takes like 5 weeks to come off of it). Mood was still stable. Dick started working again around week 2/3. Started dropping weight around week 4.
