What Christina said above. Zyprexa made me non functional. I fell asleep on my brother-in-laws shoulder at my daughters baptism party. Right there in the middle of the room, snoozing on his shoulder. So zyprexa knocks me out. Lithium is a wonder med I’ve never felt sedated or stuck while on it. I occasionally get words sort of get stuck on the way out or having to mentally search for a word or phrase, but those are really the only side effects I get from lithium. The benefits far outweigh these small drawbacks for me.
