I'm not sure where I can ask this. I got prescribed hydroxyzone. The full dose knocks my ass out. Not really helpful for emergencies which is what it's for. Last time I was on anti-anxiety meds I could split them. It seemed to help quite a bit. So my question is, can I split these? Asking here as it's a Sunday and I can't ask my doc until my lunch tomorrow due to work. 

If this isn't an appropriate question I'm sorry just curious!
