I once made the terrible mistake of buying these during camp last year, obviously I had the whole pack within about 10 minutes.
This, of course, happened to be the worst idea I had ever conceived. I ended up in the bathroom for over 45 minutes, trying my absolute hardest not to throw up. Upon returning, I had to tell my counselors that I had not realized lunch had ended in order to save myself from incoming embarrasment.
tldr; Do not ever eat an entire pack of these in one sitting, it will be the worst decision you ever make.
