It indeed was way too much for me to handle, especially for my first time. My full experience is as follows:

I took the acid at around 5:30 - 6:00PM with another friend of mine, and it was dosed by a kid who had no idea about what he was doing. Then I played Call of Duty Zombies for a little while with some friends. At around 7 I started to feel it a little bit. I was trying to jam with my roommate who had taken acid with me, and the neck of my bass appeared to be curving inward, so I had to stop that. Then I went into my friends room and stared at the pink and green and yellow step-like geometrical patterns that were appearing on the windows and walls. Then I started to overload. I was listening to my friends who had begun to realize that my trip was going bad, and while I was listening to them, I realized that I could speed up and slow down the rate at which my friends were talking to me by drawing circles in the air. Then I began to feel sick, so I went into the bathroom, and then I knelt down at the toilet and it seemed to go 2-dimensional and then dark purple and blue patterns formed in the water and then I blacked out. This is when I had my seizure and stopped breathing.

I woke up to about 3 EMT's and 3 campus police officers staring at me on the bathroom floor. At this point I could hardly communicate and they just put me on the stretcher and then I got in the ambulance and went to the hospital.

In the hospital, I was constantly monitored by one of the officers from campus, and the Spanish channel was on the whole time I was in there, and while I was tripping, I'd swear I could understand everything that they were saying, even though I hardly know any Spanish. Then I just laid back and stared at the ceiling as the tiles warped and expanded and whatnot. Being in the hospital while tripping was not very much fun, everything just seemed really chaotic and out of my control and capacitance to understand and grasp the situation at hand. Then my father showed up, because the police had called my parents. Once he got there, the officer left, and then I just chilled with my dad until about 4 in the morning when I was released.

The trip only lasted about 6-7 hours, despite the large amount I took. I assume this was because I am on an SSRI, and also because they flushed my system with either water or a diluted saline solution.

Anyway, that is really all I know about the experience, the rest of the things that happened, including the time that I was essentially out of body (I definitely experienced some intense spiritual feelings and visuals, I just cannot remember what they were), but all that remained with me after that was just a strange sort of understanding and a new outlook on my surroundings.
