If you really think your drink got spiked, go to the hospital and tell them and get a tox screen / drug panel whatever done. If something shows up, you can actually use your otherwise very hard to believe story.

Otherwise, you just got drunk and showed your true colors.

Best of luck and I hope you can reflect instead of being defensive as might be one's immediate reaction to the onslaught of negative, yet honest and accurate, comments here — all of which essentially boil down to "you're an asshole."

But remember, people aren't words. You're not an asshole. You just acted like one and perhaps continue to act in an assholian manner. People change. I would look at this as an opportunity to audit yourself, what you want, who you want to be, and how to become the good person you otherwise think — perhaps incorrectly — that you are today.
