All i have to say is: I have an allergy to certain TYPES of alcohol (no beer, no wine, no Tequila, no Vodka). It makes me SO So so so sick the next day - not what a normal hangover would be. More like an epic sinus headache. The only drink that is left to me is rum, so if it's not available, I won't drink anything because i know i'll pay the price.
So anyways, I'm at a wedding earlier this year with primarily wine / beer open bars, and everyone is like "Why aren't you drinking? are you preggers?" and I'm like "no, no, no" because it's frustrating trying to explain the whole "I don't drink x y z because I'm allergic" thing. But then they have a mojito bar, so I try to prove a point, and drink 6 (very large) mojitos, and somehow end up walking home from said wedding reception after-party bar at 3 AM in the morning, trying some parkour to vault a fence for a shortcut and majorly cutting my hand in the process, and being chased by a rabid raccoon.
