INTERESTING FACT

I thought that the hangover is really just a headache caused from dehydration.
You may say why are you dehydrated when Beer etc. is mostly water that's because Alcohol is just poison to your body and your liver syphons out this poison taking excess water with it making you pee more.
I believe this is true because people who drink more water when they drink alcohol don't really get as bad hangover.

Love the last sentence "A lot of people are also likely to become very angry and depressed after they have consumed a large amount of alcohol." We're angry and depressed because the forking sun is shining through the window, I have cotton-mouth, whishkey breath, a thumping headache and I have to go to work in 20 minutes. You douche.

i believe a hangover is multiple problems such as the headache is caused by dehydration. (drink lots of water before you goto bed to aviod this portion of the hangover) the vomiting is caused by the alcohol you have comsumed pass your liver is too hard of a beverage for stomache acid to breakdown hence the name hard liqor so you vomit. the best way to avoid hangover is before you goto bed eat 2 tylenol and drink lots of water to dilute the alcohol and eat dry toast in the morning followed by 2 more tylenol and lots of water. Happy drinking!

It is dangerous to take tylenol with alcohol.

It's not dangerous unless your immature about it. Regardless what some fool posts on ehow. ehow is not always a reliable source of information. Due to the fact that anyone can create an account on ehow and post some gibberish they read on a bottle description mixed with their own opinion, makes ehow a very bias source of information. If you were to ask anyone with a degree in medical science they will tell you it is always "dangerous" to mix any medication with alcohol. This is always mentioned due to the laws from the ministry of food and drugs. The reason they have made it law, is to protect manufacturing compaies of lawsuit if in the event that someone takes the medication while consuming alcohol and has an allergic reaction, they cant sue the manufacturing company. Though people often have negative reactions to medications while under the consumption of alcohol, acetaminophen has a reputation to cause liver damage. most of liver damage reported in the united states and most of canada had be believed to be caused by acetaminophen however studies have shown that the 96% were at a high risk of liver failure caused by the consumption of too much alcohol. alcohol takes 24 hrs. to leave the human body as alcohol is liquid based which is why people often blamed liver failure to the tylenol however studies proved that though alcohol leaves the body within 24 hrs, the damage takes years to heal and if you don't give your body time to heal, it all adds up. Sign to look for when looking for liver failure includes yellowing of the skin, nails, and teeth. for further information about these topics refer to medical journals in a library of a medical science institution before believing everything you read in ehow or wikipedia or any other bias source of information.

weed is the ultimate hangover cure. thats why its here on earth. just sayin..

The reason you get a hangover is the production of acetaldehyde as a by-product of metabolism of the ethanol.
Aldehydes are also produced and react with cell membranes and the production of free oxygen radicals is also a problem.
It's not just dehydration although that does play a part.
Drink some water and give your liver something to make the detoxifying glutathione by eating a good source of protein. Hard-boiled eggs with some hot sauce is good and so is canned fish. And take some vitamins and enzymes to help you digest it.
