Most bars will hand out water at the end of the night if you ask for it. I know a lot of places charge during the night for bottled water, but if you ask at closing for a glass of water, they'll give it to you.

The actual effects of a 'hangover' are the same a person would suffer if they went a week without any water- like lixy said, it's simple dehydration.

Eat a good non-greasy meal before drinking, pack in fluids before drinking, and chug a large glass of water or electrolyte type drink before going to bed. It's also healthier than just binge drinking, and popping a pill.
