I don't think I've ever had a proper hangover. I've woke up once or twice with a bit of a headache, but really... that's it. Half of me is way to scared to drink to the point of a hangover because I'm petrified of vomit. There is nothing worse than stomach retching, exhaustion/shakiness from retching, and that acidic burn at the back of your throat.

I don't drink on an empty stomach, and I don't drink that much. Heck, I celebrated my eighteenth with two pints for the whole evening. I turned down a drink on my brother's birthday due to an empty and shaky stomach, so I'm fairly sensible about when is a good time to drink.

Also, if you drink non-alcoholic drinks (preferably water) after every drink, you don't seem to feel the effects as bad because you're not getting dehydrated. You apparently wake up feeling rough, but not as bad as you would if you were completely shitfaced.
