For me tequila is the drinks I should never go near. I have very few memories of what happens when I drink it - but other people sure as hell do...My drink to not go near is dark rum. Had the worst hangover of my life and a few stills in my memory of a very poor pirate impression. Shudder.
A more recent one is Ameretto. Foolishly had a couple of them after a big night out and all I could taste for the next day was Ameretto. Yuk.
