I have read more than once that a hangover from alcohol; is also caused by dehydration from the liquid, and the effects it causes to the mind and body, you could drink some water , not too much, what you are comfortable with, and it puts the moisture and hydration back into your mind and body; where it is needed.

Gatorade and sleep.
Gatorade takes care of the dehydration.
And though sleep doesn't cure anything, it helps to be sleeping during as much of the duration of the hangover as possible.

I drink a half of 24 oz bottle vitamin water and keep it by the bed. i also take b-complex, potassium, magnesium, and fish oil when I wake up and again at 5 pm without the potassium. Too much potassium can cause irregular heart rythym.

it's your liver that you should be worried about,as one cannot live without the "liver."rdgrnr,go ahead drink up man!
