For me the SSRI's like Prozac have always caused interrupted sleep. I dream like crazy and wake up every two to three hours. Have to get up for 5 or 10 minutes and then can go right back to sleep and dream like crazy again. I figured out I wasn't getting any stage 4 deep sleep which is what we really need. Its hard to know because depression messes up sleep too. I really hate to take a med to solve a side effect but I take Remeron for sleep and it has worked great. I have tried trazadone, nyquil, ambien, and nothing has worked as good as remeron. I get very good sleep with it and don't feel hungover or anything. safer than benzo's or ambien.
