If you're at the point of a Hangover, there are no fixes, but there are some things you can do to make yourself feel better. For a while.

1) Aspirin.
2) Gatorade
3) Frozen Yogurt
4) Sex

The first two should be obvious.

The third goes down very nicely and coats your stomach. It's not fatty at all and if you eat it quickly enough, the cold from the yogurt settles your stomach and acts as an antacid. It doesn't work for everyone. One of my friends loved it and felt better immediately and one of my exes tried it once and spent the next half hour puking.

The last ones the important one. Find someone that will let you fuck them while hungover and bang away. The exercise helps clear up some of the toxins in your bloodstream so you're that much closer to not being hung over and the endorphins from the orgasm kill the pain for a while. (Usually about an hour or two.)

The real trick is getting someone to fuck you while hungover. It takes some convincing.
