Help! I'm Hungover. Make it stop.

Think French fries.  No really, someone told me this and I didn't believe it until I saw it with my own eyes.  The greasier, the better.  You would think it would make you more sick, but the grease actually helps deal with all that alcohol.  The inherent saltiness probably helps you with the nausea, too.  Next time you have too much, order some greasy food to help get rid of the hangover the next day.  You should be able to get some greasy fries for about $1, but it will be the best dollar you ever spent.  Next thing, hydrate.

Awesome Tip:  Want to fight that hangover preemptively?  Drink water between each drink.  Alcohol dehydrates you, which worsens your hangover symptoms a lot.  Also, it will help you pace your drinking.  A little food while you drink also makes a difference.

If you feel up for it, a little exercise will help you sweat it out, followed by a shower and a nap if you have the time.  Don't go crazy and try to work out hard.  You just need to get your lymphatic system going.  A nice walk would be fine.
