I take my entire dose of Geodon at in the evening/night per doc's instructions. I cannot imagine taking it during the day as it makes me dopey right after I take it. As a result I sleep through the night and it controls the symptoms during the day/evening. I don't know if this might help but wanted to share this just in case it hadn't been mentioned.
I would definitely talk to my doc if experiencing these side effects; please let them know this is going on so they can help adjust things. Good luck finding what works best for you.
