Have a glass of water between drinks. Don't drink coke too much after alcohol, cause it'll give you too much acid. Yoghurt is also good and easy on your stomach when you're hungover.. Don't ever take anti-inflammatory drugs, like diclofenac, for headache cause it can cause some nasty damage and you can vomit blood.. Also, what my friend said, sour cabbage juice is awesome if you want to get sober really really quick cheers.

the thing that helps me most is taking a shower. doesn't really cure the hangover but at least i'm not totally destroyed for the rest of the day..

2 glasses ice water with lemon slice and one headache pill before sleeping.

drink water during your drinking and at the end of the drinking. in the morning a very sour pottage will help your stomach.
in romania we got sour salad pottage and sour potato and meat pottage. mix these with sour cream and you're ready to go for another drinking day. this is how we do it in here, when we want to drink more days in a row.

huh kinda reminds of me lol....but dunno now on i just know when to stop drinking and such i mean ''know your limits'' i know its hard to ''feel'' them when u are with a good company, but if you start to think about next day, inmediatly you will stop, this works for me quite fine now.
