Haha, the path to alcoholism. The cure to a hangover? Being drunk. As long as you're constantly drunk you can never have a hangover!
I find I only get a hangover if i mix and match drinks. As long as I stick to one type of beer and don't overdo spirits i don't get a hangover at all. Maybe try and find something you can drink without getting a hangover afterwards.
Oh, I think general advice to this is to stay hydrated. Alcohol dehydrates you which can be the cause of headaches etc alone. Drink some water before you go to bed and see if that helps.
I did mix drinks, I'm 29 so you'd think id have gotten the hang of this by now lol. Anyways, Whats your thoughts on gin and tonic as that 1 drink to stick with all night?
