Other than occasionally nodding off on the couch sitting straight up (everything I've taken does that) I don't have any side effects from the saphris. If I don't sit still I'm fine I went off it for 3 months and was miserable, I was having a break from APs because of mouth movements. No sleep aid could make me sleep, or sleep long, I took Ambien and stayed up 8 hours afterwards reading a book once. I asked for the saphris back.
