I've been on Zyprexa full-time for nine months and was on it PRN for months before that. I recently went from 5 mg to 7.5 mg and it's harder for me to get up in the mornings. I also have some tremors, which I attribute to being on two antipsychotics because there's no other explanation for it. However, I'll put up with a little sluggishness and shaking because I don't want to feel the way I did before I went on the medication. It's a miracle drug for me.
