What’s the alcoholic beverage that made you say never again?

Long Island iced tea, I drank so many one night at a club while in my late 20s along with some tequila shots,  however I noticed after my 3rd that I was very drunk, more so than usual and started to feel sick. It came to my attention later that night that my Long Island Iced Tea had been roofied. I was never so sick as I was that night or the next day.
