Yea full gallon is a lot but alcohol is processed by time, nothing, nothing hurries it up. The dehydration effect that alcohol has on the body causes the nausea, headache etc. Sleep and water, only thing that will help. [/quote]
The effect of dehydration on hangovers is only part of the story. You’ve also got acetylaldehyde floating around from the metabolism of ethanol, as well as fusel alcohols (congeners) produced by fermentation which play a huge role in making you feel like shit the next day.
Drinking water between beers/shots will reduce the severity of the hangover, but I don’t care how much water/pedialyte/etc you down while drinking…if you’re doing shot after shot of bourbon, you’re feeling it the next day.[/quote]
There will always be metobilites floating around, if you ever took care of somebody who has had heat stress (stroke), heat exhaustion. They will tell you feels just like a hangover.
