I would have to take anywhere between 5 an 50 mgs of Zydis prn (sublingual Zyprexa) to sleep depending on my mania. Spring time is often a time when we get ramped up, and you might need a little extra help to sleep. My psychiatrist would tell me that the most important thing to keep mania down in consistent, regular sleep and to take more Zyprexa (and way safer than benzos). The more I took however, the more "hung over" in the morning I would feel.
