First "incident"!

So I had a headache the other day and I decided to take a couple of tylenol with my Crystal light. I guess I must have taken them too quickly or something. I was just sitting on the couch at the time and after a few moments of discomfort, and without any effort on my part, up came the crystal light and just poured all over me. I was so surprised because it was like I had no control whatsoever...didn't even move to stand up and run to washroom because I had absolutely no idea it was about to happen. It seems very strange to me since I've been eating real food and not had this happen. The two tylenol must have stuck in just the right way and blocked the crystal light from going down. Anyone else have anything like this happen? I guess it highlights for me the need to chew properly if something so tiny as tylenol could do that to me. Crazy!
