This sounds awfully close to my experience except I really did end up defecating myself after being drugged. I, too, went from happy dancing drunk to sprawled out on the floor in a span of 10-15 minutes according to my friends. I was dancing with my drink in front of me on a hand rail thing and did my best to keep my eye on it. The handrail was next to a table with a group of guys and girls. It must've happened when I looked away because the last thing I remember is dancing in that spot. My friends on the other hand said I joined these guys at their table and then started acting very sloppy. That's when they decided to take me home and dragged me out. Just before getting to the entrance of the club to leave, I passed out. Luckily they ran into a guy one of my friends was dating at the time so him and his friends carried me to their car and joined my friends to take me home. They carried me all the way up to my apt and unfortunately my apt unlocks with a code and because I was unable to talk or move, my friends took me to a hotel. My friend and her guy stayed the night with me, me on one bed and them in the other. When I woke up the next morning.. I was soaked in my own poop. I couldn't remember anything and my friend, not realizing I had been drugged was very upset. I tried my best to remember what had happened but I couldn't. I've been stupid drunk before, but this time was different. My mind was completely blank. I was embarrassed of what had happened, but scared that something I had only read online about had happened. But mostly I was glad my friends were there to take care of me. I don't know what would've happened if they weren't. Your friend is truly lucky to have you guys.
