Yes can relate somewhat to this, not specifically the making bad decisions part (I can do that just fine unmedicated!) but feeling like you're "waking up"... I find on antidepressants that I am just numb. They seem to suppress emotions and feelings to the point where I really don't care about very much at all.
Off them though, I'm suddenly overwhelmed with emotions and feelings that I no longer know how to deal with.
I don't know which is worse.
