I am currently on seroquel. It has not helped with the sleep as of yet but when I was on this drug last year it made me tired but still very functionable. Keep track of what you feel and talk to you pdoc if you notice anything other than being tired. That was what I was told to watch for. My doctor plans on increasing my dosage to help with sleep. I just don't want to be a zombie so we are taking it slow. You are doing the right thing by asking for information from some users. WE can be honest with you and let you make your own decision on the drug.
