A hangover is the sum of unpleasant physical effects following heavy consumption of alcohol or the use of other drugs. The most common reported characteristics of a hangover are feelings of extreme thirst (dehydration), feelings of being more tired than usual, nausea and headaches. In alcohol metabolism, one molecule of ethanol(the primary active ingredient in alcoholic beverages) produces 2 molecules of NADH, utilizing Vitamin B12 as a coenzyme. Thus, Vitamin B12 deficiency is a proposed cause for commonly experienced hangover symptoms.
Common folk medicine has a wide variety of hangover cures. A good hangover cure should replace essential nutrients lost by the body while counteracting the influence of residual poisons; very few cures do both at once.
Among the more common proposed cures are:
drinking a sports drink (not an energy drink) such as Powerade or Gatorade, usually watered-down to rehydrate and replenish lost nutrients in the body. Powder supplements such as Ultima Replenisher contain a higher amount and better balance of electrolytes without high levels of sugar.
Pedialyte contains more electrolytes than most any over-the-counter substance. This will help you re-hydrate your body as quickly as possible.
drinking a large amount of water before going to bed, and during the night, for rehydration (a little water is much better than none)
eating as much food as you can hold down. your pyloric valve will shrink in response to the large amount of food you consume thereby reducing any further absorption of alcohol. a large meal is likely to contain nutrients to replenish your body and may also cause drowsiness which will help you sleep while your body repairs.
eating mineral-rich foods, like pickles or canned fish
drinking pickle juice, the solution in which cucumbers were pickled, in the morning (a staple hangover remedy in Poland)
eating anything substantial, especially before going to bed, to "soak up" the alcohol in the stomach (e.g. a pizza or sandwich)
orange juice, which is rich in vitamin C
taking a vitamin B1 (thiamin) supplement before going to bed
(instant) chicken or vegetable soup provides salt, proteins and electrolytes which help attenuate hangover symptoms
Irn Bru is commonly regarded as a remedy in the UK.
cysteine, which is available as the over-the-counter supplement N-acetylcysteine (NAC), is known to assist in processing acetaldehyde, best taken while already drinking and/or before going to bed. (Egg yolk is also rich in cysteine, and it is notable that many hangover folk remedies or morning-after breakfasts incorporate eggs.)
consumption of an Ulster Fry (popular in Northern Ireland), an Irish Breakfast or a Breakfast Roll, a meal that is an all day breakfast.
day/night cold and flu tablets
though illegal in many places, smoking marijuana is often used. This is related to the wake-n-bake.
taking a dose of ibuprofen before sleeping can reduce hangover effects dramatically, however this may increase the risk of stomach ulcers
maybe this will help
