The very worst i have ever been was one night, back in 1997, where i went out, drunk a lot, started with absinthe...and was under medication....not a good combination.
I don't remember half of the night...but i know that i was banned from the bar i went and wanted to pick a fight with the security.
Nothing happened because i was with friends and they had by back and calmed the situation.
I only have flashes of that night, i remember waking up, going to the bar, and drinking 2 or 3 Flaming B-52 and breaking the glasses by throwing them at the wall.
I was THAT f***ed up...
Even so, the next day, i didn't got nauseous or vomiting.
Believe me when i say it was a one time event, i rarely drink...except when go out, which is not that often.
And even when i drink, i have a very high tolerance for alcohol, so, even when "drunk", i'm very controlled of myself.
It was the alcohol and medication mix that did that crap on me, and i believe it wasn't much worst because of my very high tolerance.
