With all due respect to all the smrt guys in here, OP, you are in a chat forum on a steroids board. There's obviously a reason you're taking seroquel and I don't think a test booster will hurt you but is this really the place to be asking? Seroquel will make you tired, for sure. Could you look at a medication that doesn't have quite the sedating effect? If it works for you, though, tough to mess with it too.
