I like to drink Pedialyte, it helps a lot.

1) Sleep. Once you awake, go back to bed. Sleep at least 12 hours.

2) Take 800mg of ibuprofen when you have that brief wake up moment. I would l also drink a 1/2 cup of liquid antacid.

3) Once you are finally awake for the day, take a really cold shower, or if you have access to a pool, take a dip. Do this periodically as needed until your hangover starts to disapate.

4) At anytime if you feel like vomiting, don’t hold back. After the vomit, you will feel better.

Drinking water between drinks is also a great way to prevent the ailing morning-after effects.
To help avoid a hangover, try to eat or snack before or while drinking.

Now if these suggestions didn’t work or if you didn’t follow these tips, here’s how to handle the morning-after hangover:
The symptoms you’re feeling post-drinking are signs of dehydration caused by the alcohol. That’s why you must rehydrate yourself by drinking a lot of water when you get up.

Rehydrating your body is the key to recovering from the hangover, and this cannot be stressed enough. You can even put some lemon in your water, it’ll help soothe your stomach and will add vitamin C.

When drinking water, avoid water that is extremely cold or hot; drink water at room temperature.
Even though you’re extremely tired and a cup of coffee seems like the best way to wake you up, try to stay away from it.

Caffeine will only dehydrate you more, and since it’s also a diuretic, it will not help your stomach. Milk and other dairy products are also not a good idea; they may make you feel more queasy.
If you don’t want to drink water, try a glass of flat ginger ale, which helps soothe your stomach.
Juice is also a good idea; vitamin C will help give you the energy you’ll need.
Sports drinks such as Gatorade have been known to work for some people.

Have an over-the-counter painkiller such as aspirin or ibuprofen, to help ease the headache. Do Not have acetaminophen-based pills; these can be dangerous when mixed with the alcohol in your system. Take the pills in the morning, not before going to bed when the alcohol is still prominent in your system.
Either sleep in, or wake up and take any of the above-mentioned measures and go back to bed. This is assuming, of course, that you have the luxury of sleeping in for that particular day.
Another effective way to alleviate the pain is to lie in a dark room, with a cool compress on your head.

these are tried and true

Water (Lots Of It)
Funny as it sounds, drinking alcohol actually dehydrates you. Take beer: It’s mostly water, but the alcohol in it blocks hormones in your kidneys that normally would keep you from racing to the bathroom all night. With each beer (or dreaded shot), you effectively lose more water than you take in. As your body dries out, bad things happen, including those searing headaches. Drinking water the next morning helps, but it’s best to interrupt your bender with a few glasses along the way.

Sports Drinks
You not only lose water when you booze, you also dump electrolytes. These salts and other minerals keep your body functioning properly. Sports drinks like Gatorade help replenish these reserves

Over-The-Counter Pain Relievers
Everyone has a favorite, be it aspirin, ibuprofen or acetaminophen. These pain relievers can stave off hangover headaches, but they can also do a number on your liver when mixed with alcohol–especially those with acetaminophen such as Tylenol and Excedrin, which throws in a dash of caffeine for an extra perk. Use judiciously

Vitamins B6 and B12
Lower levels of vitamins B6 and B12 can intensify a hangover, says Dr. David Katz, director of the Yale Prevention Research Center. Alcohol inhibits absorption of these compounds. Supplements taken the next day can speed your recovery–but don’t take them all the time, he warns, as excessive amounts have been linked to long-term nerve damage.

Berocca
Veteran booze-hounds in the U.K. and Australia tout this Bayer-branded multivitamin–not available in the U.S.–as a powerful hangover antidote. (Bayer doesn’t exactly market the product that way.) The tablets include vitamins B and C, magnesium, zinc and assorted sugars and salts that your cocktailing robbed you of the night before.

Prickly Pear
You won’t find water in the desert, but you will find another hangover cure. A recent study by researchers at Tulane University found that extract from prickly pears–a species of cacti–ameliorates a few hangover symptoms such as nausea, dry mouth and loss of appetite. Check out Perfect Equation and other vitamin companies for supplements. Note: Prickly pear extract doesn’t work on headaches, so you might still need to reach for the aspirin.

Tripe Soup
Here’s a good one, if you can stomach it. Folks down in Mexico swear by tripe soup, made from the lining of a cow’s stomach and spiced with chile, garlic and other seasonings. Don’t look for hard science here: More than likely, the sting of the spices provides a welcome distraction

Haejangguk
In English, this Korean dish literally means “soup for the stomach.” Street vendors in Korea sell it out of carts, usually on weekend mornings. The ingredients vary, but cow bones and cow’s blood are mainstays, along with a collection of spices that would make most Westerners scream. But better a stinging tongue than a throbbing temple

Rosiglitazone
Know any diabetics? They may have a bottle of this stuff hanging around. Rosiglitazone eases hangover symptoms by boosting glucose levels. But don’t count on this prescription drug coming to market as a hangover cure anytime soon. In general, diabetics should avoid alcohol. (Obviously, consult a doctor before you try this remedy.)

Hair Of The Dog
Legend has it that a morning nip can keep a hangover at bay. But far be it for us to put you on a slippery slope to dependency. my suggestion: a plate of greasy eggs and bacon.
