Might be wiser to push your birthday festivities to Friday and just have a couple of beers with your friends tonight. Better yet, you should probably study for your exam.

Honestly ya know what helps me when I'm out drinking? Walking home. Downtown for me is only 45 minutes walking, but no matter how trashed I get as long as I walk about half an hour distance I've noticed I'm not sick the next day and sometimes I'm even sobered up by the time I get home, just hungry. A couple weeks ago I had no choice but to take a cab with a buddy who lives right near me and I was pukin' that night and well into the morning then dry heaving by the time my son was dropped off. Every other time I walk and I'm right as rain. PS. Happy birthday, man! I baked you a cake with a stripper in it! but then we had to return it after it turned out the stripper didn't know to get in AFTER it was baked =( Hope it's a good one!

Loud music and a lot of screaming and jumping always helps.

Drinking a lot of water kinda helps. Just google hangover cures, you should find something useful

Cold showers and food.

As soon as you get home, drink lots of water. Drink as many glasses of water as you did beer if you can remember when, or better yet, ask for some water before you leave the bar to start you off.
Second, most likely when you wake up in the morning, drink orange juice, and eat some fruits (best ones are bananas, blueberries, and pineapple) to replenish your body with some great vitamins. If it makes it easier for you, just blend all this stuff together into a fruit smoothie before you go out, and drink it when you come back, or when you wake up. Take an Advil if you're still bring bothered by head pain, and eat some buttery toast. You'll feel right as Rain.

I always eat toasted bread. It helps immediately.

But I would not celebrate the night before if I was you. I did that once freshmen year and got a B+ in a class I should have gotten an A in. And then I did it again sophomore year and got a C+ in a class I needed a B in. I had to retake the second class. It's not worth it in the end. Well for me.

The best cure for a hangover is to not drink.

How did the exam go?

passed exam, completely wrecked though haha

I approve this message. Happy belated 21st.
