I had a similar experience as Rob P with Jack Daniels, but with tequila. A company Christmas party at a club, everyone ordering shots of tequila, and most of the ladies passing theirs to me after the first one or two. I have no idea how many I drank, but I was singing to my wife in French on the way home, and I hadn't spoken any French since 1972 in Viet Nam....and I was violently ill and felt like death-warmed-over all the following day. (I do not normally get hang-overs and can recall only 2, ever.) It took me a long time to even be able to drink a margarita and I still can't touch a shot of tequila - the smell makes my stomach churn, violently.
