Have you ever gotten blackout drunk before? It isn't fun. When you are to the point where your body is trying to eject stomach contents you are in pain. The world is spinning, your insides feel like they're falling apart, you sweat, you can't put two thoughts together but somehow your brain will manage to make you think of crazy stuff, and all you want to do is go back in time and stop yourself from drinking in the first place.
If it gets bad enough your body can make you vomit through antiemetics and there is no guarantee you will die. Most likely you will wake up hours later with an amazing hangover and feel even more like dying than you do now. It's a wild story for a college weekend, it's not a viable ctb method.
