Saphris
"Works great for sleep and controls mania well, but caused my depression to increase.  This was after being on the medication for several months (10mg/night).  Didn't particularly like the next-day hangover either.  I've recently been switched over to Lithium but it's too early to tell how it's working.  I took one Saphris tablet last night per doctor's request, after being off it for some time (as a sleep aid) but felt hung over and a bit depressed most of the day."
