Berserk medicine is a one time item only, you can't get it twice in one rebirth as of right now, its almost a joke item.
so yea essentially Kinda no
looking at the configs folder... This medicine will...
Will maximize drug addiction = You can't cure this normally as far as i know, but elise can.
Max Defecation = Just shit
Max Urination = Just piss
Max Lactation = harmless at most cases, should go away over time.
Max Puke+Sick = idk? but Blue Potion will cure 80% of this problem.
Max Arousal = Just masturbate
there will also be a confusion hit because of Drug addiction kicking in, i dont think you can cure that, just leave the map or sleep, it goes away when map updates.
Yea this config seems like a joke item to me, use it only for humor.
