Yeah...idk actually for sure. I'm on 5 but I'm careful only take the bezo when or if I'm hungover. I usually don't sleep well the night I've drank. I'm careful...I'm on Zoloft, benadryl, buspar, and lorazepam for sleep. So only four. I take risperdal too but haven't for a couple days, I'm on a high from this guy, lol.
