dude I get hangovers soooo easily, but not any more. to cure a hangover you really need to fight it before it happens. before you go to sleep you need to do a couple things. first, chug a shitload of water. if this makes you puke, good, because that means you were too drunk and more alcohol is just gonna make things worse if its sitting in your stomach while you sleep.
Im a fighter when it comes to puking but I will admit sometimes I am really happy the big pile of beer/vodka didnt sit in my stomach as I slept. once you have chugged your water/failed and puked, find some food. brush your teeth, and drink more water.
when you wake up, drink some coffee and shower. if you followed the above directions you would have to have been hammered beyond all belief to have much of a hangover. if you still have one, drink some water and smoke a bowl.
