Tylenol and tons of old fashioned water, {I do un sweetened iced tea with lemon by the quart, this also helps with the tiredness.... }
But the most important thing to remember is hydrate while drinking the night before, start the night with a bottle of water, drink another half way through and just power through a couple bottles right before you crash....
About a year ago, a friend of mines 17 year old daughter came home drunk and sick, he called me and had me come over to help him deal with it {his wife passed the year before at 39 years old}, I got there and she was really sick, she weighs about 90-lbs and drank hard liqueur all night.. So I seen she wasn't even throwing up and was passing out so we took her to the ER for a pump out, but when we pulled in the parking lot she started vomiting so they didn't have to pump her stomach but gave her an iv of saline and within 15 minutes it was like she never had a drink, sober and feeling hungry {still had vomit on her shirt}!!! I couldn't believe it, but the dr said it happens all the time, dehydration causes most of alcohols effects and saline fixes it within minutes...
The dr did ask Jimmy if he wanted her to feel better or learn a lesson, but I said considering what she had been through in the last year, she deserves a pass, teach her a lesson next time, so they gave her the iv and took her for a walk around the er showing her all the other drunks and what she looked like 30 minutes ago... {there was actually 2 more kids there from the same party she went to.....}
anyway, drink water, and don't eat red meat, anything sweet, anything fried , soda... that should go for everyday actually, lol...
