I am on a high doze of olanzipine and am feeling drowsy and unmotivated. I find it hard to get up in the morning. Is this side effects of the medication or am I suffering with depression. I am currently not taking any antidepressants as there was a worry it would trigger mania again. I am finding things really hard at the moment. I'm hoping that a reduction in olanzipine will help my mood and give me more energy.
