I suffer from severe depression and anxiety even when I wasn't using. I was on Prozac while drinking and it didn't work, so I thought it sucked. It works A LOT better on sobriety. However, even on the max dose I still experience the typical ups and down of life. It's not like a narcotic or alcoholic where it gives you that euphoria but it certainly helps balance things out. In my case I had to go on another medication called Abilify to help the Prozac out but most people the Prozac alone will be enough. It certainly helps me, I don't think I would have stayed clean with out it due to the fact that I was using to self medicate in the first place.
