When I am closer to mania, caffeine will make it so I can't sleep.
As I get closer to normal I can have caffeine without any ill effects.

I am on Zyprexa only. 10 MG.

I just recently escaped a manic phase where caffeine was really powerful. Now I am pretty normal and caffeine does not have much effect. However, I am getting my caffeine from tea and chocolate so I am not intaking a lot of caffeine.
