If you take the haldol properly for a couple of weeks to a month or so the drowsiness should wear off. Considering you're not finding college very challenging and you're ahead it might not be a bad time to start taking them. It'd be different if you where working and you can't afford to be drowsy. It's worth a try. I can think of worse states to be in. The chlorpromazine I'm on doesn't make me drowsy anymore and I've heard it's the same with other AP's.
