The last time was about 8-9 years ago. I had eaten a frozen pizza that made me really s*. I woke up in the middle of the night, totally freaking out. I had to go get my mom because I wasn't even sure what to do.
I don't really remember too much of the actual v*ing or anything...I guess maybe I blocked it out. It was scary due to the fact that I was asleep. Otherwise I may not have ended up with this phobia at all.
