I'm not sure what it is, but if it's one of those drinks, it's just some diuretic. Keep drinking lots of water and cranberry juice. When you're taking a test, you really only have two options, substitution or dilution. If you don't have someone to piss for you, or can't get Quick Fix, then make sure you piss water. Take one of the mega man vita-packs from gns and you'll piss yellow like no tomorrow.
