Oh girl, been there sone that lol. Heck im 24 and "over do it" sometimes. Woo it's fun to get a little sideways sometime. Lots of water and head ache medicine before you go to bed. Have fun!!! Don't drink and drive!
Here's my tip...you are 21, not 14 - use some common sense. Most things are OK in moderation. It is one thing to drink socially, unwind, and have fun, and quite another to get drunk and sick. The former is responsible, the latter is irresponsible, and hardly reflects adult judgment...
Pace yourself and never switch alcohols. I don't drink at all anymore. I over did it when I was younger and now just the thought of drinking gives me a headache. I think i've had maybe 3 coolers in the last 2 years lol.
Anyway I learned that if you commit yourself to one type of alcohol it lessens the hangover. My choice of toxin was always vodka. Avoid anything super sugary, make sure you have food in your system. Eat something starchy before you go to bed along with 2 advil or tylenol and lots of water. In the morning if you are hurting add a pinch of sea salt to a glass of water and keep drinking.
My friend convinced me to do a shooter the following morning when I was really hung over. It actually worked. But really... I don't want to keep drinking when I feel like crud lol
I'm at the point now where I hate drinking. I can't even stand the smell of alcohol. I think I partied myself out in a big way in my younger years.
Once I got really sick and decided that I never wanted to do that again. After that, I would finish my drinks slowly and, if I started to feel just a little too drunk, I would switch to either Orange Juice or pop for the next couple of drinks (2 drinks would last me an hour or so), then I might go back to alcohol, depending on how I felt.
That alone kept me from having hangovers, but I would always take a couple of painkillers and drink a large bottle of Gatorade just before I went to bed anyway...to be sure I wouldn't wake up with a headache.
I never thought of drinking water between drinks, but that makes a lot of sense so long as your city's water doesn't taste nasty.
I don't like overdoing it. Not only does the hangover suck, and getting sick suck. I can't sleep when I'm drunk. I get a horrible case of vertigo and spend more time then not wandering around all night long. I've always been one for moderation for the most part. Every now and then I would forget how fast I was drinking and by the time I started to feel it, it was too late and I would be pretty drunk. Happens a few times after showing up at parties where everyone was already into it and didn't like the fact that someone was sober...and everyone wants to pore shots.
Nurse your drinks. At parties beer cans are my favorite to carry around as no one can see how much (or in my case how little) I really was drinking. They offer a shot, I hold up a beer can and say I'm good.
FOOD. I have found I can handle my drinks a lot more if I have eaten good hearty meals throughout the day. My friends used to tell me greasier the better. We would all go out for fast food burgers before going out. It always helped.
Then be hydrated before. You can water it down as much as you want while you're drinking. But if your body is dehydrated already the water you drink then won't help tons until later. Then drink water with your drinks. Hydration is huge too!
I agree with NBEventer, stick to one drink if possible.
But overall its just willpower to realize how you are feeling and be strong enough to say no. Realize it takes a little time to feel the alcohol. So don't keep downing stuff until you know how much your last drink is getting to you.
Go slow, drink water, eat food before and be smart.
