How long have you been drinking? When you start you tend not to get hangovers. When I was 15-16 and was guzzling cheap vodka on a golf course I rarely felt too bad in the morning (with a few notable exceptions). These days I will get some pretty monstrous hangovers if I drink a lot, and I'm 19 now. Four years of drinking relatively heavily will take it out of you, I promise you. I can beat them by sticking to spirits, drinking water before I go to bed, accepting that I will wake up at 6:30AM and that I must have bacon, but I only really manage that when I'm at university. I find if I'm sick I'll feel better in the morning, and when I'm in that state I won't remember anything so I don't really care.
Unfortunately I don't usually manage that when I'm not at university- I was at Download (hell yes I'm bragging, it was awesome) last week and drank 9 litres of wine over 5 nights, sleeping in a tent and only eating cold beans and tinned fruit. If you're going to tell me that on the last morning after 5 nights of heavy wine drinking you can wake up in a boiling hot tent, find you have no water and still not have a hangover, then you're some kind of weird drinking robot set from the future to make us all look like pussies.
That said, some drinks give me worse hangovers than others. Wine always makes me throw up if I drink a lot of it, and the hangovers are fairly bad. Cider tends to give me the worst hangovers- it doesn't help that it makes my hangover piss smell like chemically death, and if I stick to spirits then I'll probably not be too bad. Alchopops will give me pretty bad hangovers, but they're cheap as hell in clubs and easy to drink, so it's a fair trade if you have to go to those places.
