I’ve learned just not to eat or drink anything many hours before I plan on going anywhere. This is the only way I can do things without spending my life in the bathroom the whole time I’m out.

Seems like the majority of people I've read about on this site have IBS-D. I'm just the opposite, I have IBS-C. Still, when I travel or run nearby errands the first thing I look for - where is the nearest restroom.

I totally know what you are talking about. I have had IBS-D for 46 years now. It is know way to have to live. When I first got diagnosed I could tell when I was about to have an attack. And I too would just not eat if I was planning to go somewhere. Then it got to be surprise attacks at the worse possible times. Some of them were pretty embarrassing. I have tried medication and eating this and not eating that until I have decided no matter what nothing is going to work. I have been to several Gastroenterolgy and internal medical doctors, so I give up This is my life and I just have to deal with it.
