That is the law, according to the rules.

Drinking is fun and all, but often leads to hangovers. I know this from experience. Like, lots of experience. And so, that said, here are the 5 Worst Hangovers. Avoid them at all costs FOR THE LOVE OF EVERYTHING HOLY OMFG.

1. The "Tequila is SO GOOD, YOU GUYS" Hangover

This is how it happens. You go out for Mexican and they're having a special on margaritas. "I will have a margarita," you think, and so you have one margarita and that turns into several margaritas and then THAT turns into, "HEY! Why not do a shot of tequila?" and this is where it all goes wrong because even one shot of tequila is enough to wipe out an entire evening.

2. The "I Can Drink However Much I Want, It's Just Beer" Hangover

You know how sometimes you and your friends will split pitcher after pitcher of delicious beer? And then, after a while, that beer tastes just like WATER and boy, are you thirsty. Yeah. Beer still has alcohol in it, dumbass.

3. The "Let's take shots!" Hangover

This is especially dangerous for those who have been out of college only a few months, but have cut way, way back on their drinking (as a result of not being in college anymore) and THEREFORE they don't have the alcohol tolerance they used to. This also affects many, many bachelorette party-goers. BEWARE THE SHOT.

4. The "I Forgot The Rules of Mixing" Hangover

Beer before liquor, never sicker. Liquor before beer, you're in the clear. These are important sayings, having been passed on throughout the generations, but not everyone listens very well. You should, though. Also, don't mix a whole bunch of different liquors in one night. Stick to one. Don't say I didn't warn you.

5. The "I've Been Drinking All Day But Haven't Eaten Any Food" Hangover

Seriously, eat something. Idiot.
