I used to be the same way. The more frequently I drank, the more I started to get hangovers. Then I went through a period of time junior year of high school where me and all my friends got into 4loko and that's when I first started to really get them. Then as I aged we started cracking 40s. Nothing is worse than malt liquor hangovers, be it hurricane, camo, colt 45, or steel reserve. Now, every time I drink anything besides classic hard A like Jack or Hennessey, or IPAS, I get a vicious hangover. And I've also grown to notice the more frequent I drink, the worse my hangovers tend to get. (Once a month vs 4/7days a week) so I think it has something to do with the condition your liver is in. Not getting hangovers early indrinking careers is common, so it's possible you have just been taking care of your body in between drinking sessions and never accumulated any serious damage.
