Remedies for your poor drunkard head.
Hot chicken noodle soup. Replenishes salt and fluids while the warmth settles your stomach. The noodles are easy to digest, and the protein in chicken chunks may help replenish the substrates that run the aldehyde dehydrogenase.
Stop drinking a couple of hours before you sleep, so you still enjoy your drunkenness but don't stick even more poisons in your body that you're going to miss the benefit of because you're unconscious (also delaying your hangover by a few hours), and instead give your body a head-start on your hangover, so by the time you wake up it's a couple of hours less severe than it would have been.
Drink a pint of water before you go to bed (salt optional, but not a bad idea), or some other isotonic/mineral-rich drink like gatorade, to replace lot fluids and salts.
Drink an alka-seltzer followed by a mixture of half Coke and half water. The sugar and caffeine will give you a bit of energy and settle your stomach. Nibble on some pretzels or saltines, taking things very slow. Nap at will.
Basically, eat the same thing that you will after a stomach flu.
If you drink a lot, before you go to bed drink a glass of water with a pinch of pepper and a pinch of salt and it will prevent the hangover.
Eat a big, greasy, protein-rich breakfast (fry-ups are perfect for this) to mop up any remaining alcohol lurking in your stomach, replace more salts and give your stomach something it can quickly digest to give you some quick energy to get you back on track for the day.
Eat a pickle/take a shot of pickle juice in the morning to settle your stomach.
Take a swim in the ocean.
Coconut water and wonton soup.
A lot of water and Vegemite toast.
A pack of bacon, some bread and muurcold whip.
Pot + VitaminWater + Coffee + Bacon Egg and Cheese Sandwich = Hangover Cure.
Water the night before, bacon the morning after.
Drink tons of water before bed. If you wake up to pee at some point, chug a bunch more water. Also, eat a banana before bed (or make a smoothie if you can). The potassium is great for helping hangovers.
If you wake up in the morning still hungover, drink more water and eat something greasy and salty- preferably something with fried potatoes. They're easy to digest and have the carbohydrates, salts and fats you really need when you're hungover.
Hangovers are generally a combination of dehydration and electrolyte imbalance (due to the diuretic effects of alcohol). Fix that and you can fix your hangover.
You'll need a multivitamin. Take it right before you eat the following: any kind of pickle, drink some pickle juice, eat potato chips, make a nice greasy grilled cheese, and have some cream of chicken soup.
Eat something before you go out ("line the stomach") so that the stomach closes off for prolonged digestion and digests the alcohol more slowly, giving your body time to mop up earlier booze before the later drinks get digested. If you don't have time to eat, try a glass of milk as the fats in the milk also cause the same delayed digestion.
