I've heard that its possible to be so afraid to v, so determined not to do it, that the part of your brain that controls the act of v actually sort of shuts down, so that times where you might need to v, you will not, which is why emets will often go 10, 15, 20+ years without v, because we are so afraid, that we subconsciously won't let ourselves do it. **slightly graphic** for example, I was once so sick and I kept gagging and dry heaving but refusing to v, and I finally tried to just give up and do it but I couldn't. I was trying to force myself to v while in the act of gagging and I couldn't. That was the only time I ever came close to v in 16 years. Any opinions?
