The last time I went to the dentist, just for a check up, as soon as I got called back, I started freaking out and had some major bathroom issues. It was before we got started, so I just asked if I could use the bathroom first. So, I did that, and my stomach still hurt for the rest of the time, but at least it was a check up, and nothing long like your appointment! You should be proud of yourself! It's a great feeling to overcome this illness! Sadly, my fear of another attack while being "trapped" has kept me from going back....It's been about 2.5 years....
