I can't speak for everyone or every medication, but I think I'm about the best I've ever been, in key ways, now after about 15 years of taking medications. Any changes, in my case, were from my illness itself (trauma and similar).

I think good therapy worked well can also be highly helpful. It has been for me.

You can try the punching bag idea, but I wouldn't. I find managing anger in more therapeutic ways better. I refer to challenging dysfunctional thinking and similar techniques.
