(TheDrinksBusiness) - Many of us have a routine to get over the dreaded hangover and the drinks business has put together the top 10 cures for alcohol induced pains. A hangover is caused by a combination of the toxic by-product of alcohol metabolism (acetaldehyde), dehydration, and Vitamin A, B (particularly B6) and C depletion caused by the chemical action of alcohol on your system. The symptoms are usually a dry mouth, nausea, fatigue, dizziness and headache and are caused by a combination of these factors. Treatment involves rehydrating the body so it can deal with the painful symptoms – though the best advice seems to rehydrate before going to sleep.
