Nah, not strong enough to be LSD. You were very drunk and unused to it. Binge drinking can cause hallucinations and all kinds of things, and the hangover is longer for those who are unused to drinking a lot. Alcohol is one of the least pleasurable drugs to overuse, so I've always wondered why people repeat the bad experience. Hope you don't.
Well, it's really impossible to say. Sounds like you were VERY intoxicated, and if you were seeing colors and shapes, then it's plausible that your drink was spiked with LSD.
The only thing I could tell you is the obvious, is that drinking to such a level of intoxication is just bad news. It's dangerous, it can put you in a precarious position to become a victim of a crime, or of an injury or health consequences. Plus, if you are prone to anxiety or depression, alcohol will exacerbate those symptoms dramatically, sometimes for DAYS after a drinking binge.
I would caution you to either stay away from alcohol (not to mention people who would knowingly give others a drug without telling them FIRST), or only drink in moderation. If you feel you have a problem drinking, then you may want to seek out help for that.
Good luck.
