Kinda late to ask but

If you get drunk faster at that altitude because of the thin air. How bad are the hangovers the next day. Not as bad since you didn't drink as much or worse cuz that is just the way it is.

Worse.

Aspirin and water.

A while ago people laughed at the picture from GOX in which glasses of water appear next to the beer.

Dehydration makes hangovers much worse at altitude, so make sure you drink water. Drinking it the next day doesn't work, you have to stay hydrated as you drink your booze.

And guzzle alot of water before you goto bed.

Your going to be pissing alot anyway.
