trouble sleeping

Last night I tried to go to sleep for 4 hours, and finally slept fitfully. I have been on Geodon 2 weeks today and this is becoming a problem. I also take 150mg of Trazodone to help me sleep. Is there anything I should try? I tried taking it in the morning instead of the night and it made me a blithering idiot -- unable to drive, exercise, or do anything but go back to bed and try to sleep it off. After 2 hrs I was back to normal, thank god. I am thinking of trying Benadryl at night also. What do you think?
