My worst drunk ever was when I was about 19.
I attended the Xmas part of the company I was working for, and indulged in the open bar.
My girlfriend of 3.5 years at the time was with me. She got toasted too.
....I go to the bar and get a few more Long Island Iced Teas and kick back with my girlfriend at a table, finish our drinks, dance a few tunes, and then start on our way home. Should have taken a cab, thank God no one got hurt or arrested.
We get back to my parent's house, go to my room, get busy. Then we try to go to sleep. Bed spins! GF ends up in bathroom, I end up passing out. Next morning is very painful, worst hangover EVER. I drive my GF home, then go back to my house to sleep off the pain. At 4:00 PM my Dad storms into my room and tells me to get my ass out of bed and study for my Chemistry final exam which was known to be the next morning. I am forced to make coffee, eat Tylenol, and sit at the table with my book open "studying."
Barely passed the test, barely passed the class, headache lasted all of Sunday. Not a good move on many counts, but I lived to tell about it!
