So I've been on Geodon for several weeks, but for a couple of weeks I've been taking it wrong and it made me manic. This is the fourth day I've been taking it correctly, but I feel tired during the evening. Is this normal or will it go away eventually? I can't be tired at night because I have homework and such to do.

I'm taking the lowest dose twice a day. I take one pill at breakfast then one before 5pm.
