YES! I had it happen to me once. I hate to admit I am an addict, ( sober 22 years) so it did not knock me out as I had a high tolerance. It did however make me loopy as hell. I was sober amazingly enough when the drink was given to me, and since I was a professional drug tester at the time, I realized pretty quickly that the few sips of my beverage had given me the "wrong" type of buzz. I was able to tell my best friend, and the two guys who had given me the drink followed us, but somehow we managed to get rid of them and went home to Lafayette. I am grateful that I was a junkie. I might have not remained awake and able to alert my friends.
It is highly probable that this happened to her. Just so you guys know, I realized that in the first pic on university? She is stopped. We all know she felt bad, maybe she was drugged and felt "woozy".
