Me too nearly always first thing when I have an attack - typical for IBS more a problem in the mornings. Yes I know we are talking about these very personal issues, but I think this is why this forum is so important.
My worst attack was three years ago when I still had heavy periods. Day 2 it was in Tucson - my son lived in Arizona then (now lives in Hawaii). We were going to fly home that morning, and my son was driving us to the airport. He is very laid back, and said we had plenty of time, but I thought time was tight. It was 5am- absolutely beautiful day there- sun was just coming up, desert was in the distance, cacti as big as houses lined the route. However- I had period day 2, loose bowels and urgency, and how I got to the airport without having an accident I will never know. I was also very grief stricken leaving my son, as anyone who has a family member living abroad will appreciate. I just got to the toilet in time, only just, and my goodness was I ill. I think it was a combination of heat,rushing, emotions and hormones not to mention different food and eating times. Probably my worst event but there have been more so yes you are not alone. It is more common than you think, people don't talk about this much and suffer in silence.
