That's all good advice. I have used the bathroom when the seatbelt sign is on, and flight attendants have not cared. I felt they knew I would only do that if I really needed to, there are lots of people with problems like ours trying to travel.
Immodium can help, and eating just a little something bland to keep acids down helps me. My doc game me an anti-anxiety drug, but I don't think it did anything. I would use Depends if I needed to, too.
Another hint: check out where the bathrooms are on that kind of airplane (you can find it online), and get an aisle seat near them. For example, Midwest's bathrooms are only in the back of the plane, and since they serve food, and drinks, and cookies, the service cart can block the way to the back of the plane for much of the flight. So get a seat in the very back!!
Thank goodness they no longer make us stay in our seats 30 minutes into and out of D.C., that was torture!
