I've been taking it since friday March 25,2011. I was on Serquel 150mg and just discontinued it the same day I started Saphris. After sleep on 3 to 4 hours a night since last Friday I took Ambien last night and was able to get 9 hours of sleep. I take 5 mg Saphris in the morning. I scared to take it at night due to the fact I lost so much sleep during the first 5 days of being on Saphris. Any suggestions comments, please help!!!
