My ability to go definately varies day to day unless I'm spending the entire day at home, then I'm like clockwork. I eat breakfast then within a half hour or so I go. Sometimes I even go again before lunch. If I have to be somewhere, I make sure I have two hours after breakfast so I'm not panicing. Sometimes it works out, often because I become so anxious about it, it doesn't. For instance, if i know I have to get in a car and drive for several hours (family vacation, weekend with friends etc) I get extremely anxious and often am unable to go even with the extra two hour time frame. Often, the entire trip is sabotaged because I can't go at a gas station or rest stop or even a restaurant. Ususlly on trips like that where there is a schedule to keep, I'm so anxious and stressed out, I feel it would have been better had I stayed home. Also, in regard to a "safe" situation becoming unsafe, that does happen to me. I was staying at one of my family members house one time and so was just one out of town guest, whom I knew well. Because of the presence of that person in the house I had a very hard time going. I was finally able to go in an out of the way toilet in the cellar. It's so frustrating!
