I have been taking by Rx 5-20mg zyprexa zydis for 20 days due to rebound insomnia. I called Dr and he put me back on zyprexa. It is the only thing that helps me sleep but I need to get off of it. Every night I go to sleep I never know how much I need. I am Rx 30mg Restoril, 50mg Vistaril, 5-20mg zyprexa depending on each night, ultracet and 1mg cogentin. I might take my klonopin tonight and skip the zyprexa. Will I have any withdrawls from zyprexa? Can I take Rozerm instead of the zyprexa since I have been on it only 20 days?
