I was on Saphris for a little over a year. It was pretty sedating. I also used to have bizarre dreams. I never had trouble getting up when I needed to, but I also made sure I got into bed early enough to get up whenever I needed to. Trying to work on 3 1/2 hours of sleep on any antipsychotic is asking a lot.
Saphris ain't got nothin' on Seroquel when it comes to being comatose.
