Do your "waves" feel like your pouch is in an elevator ride and the bottom just dropped out and it is in a "free fall", so you tighten and squeeze your sphincter to keep it all in?

That funny sinking feeling is soooo hard to describe, but that is the best that I can do.

When I have the feeling of bad pressure its usually the result of a lot of gas build up that's how I actually determine whether I'm going to take the chance and try to pass gas before I run to the toilet. I realized I can only pas gas if I'm laying on my right side or laying on my back with my knees up so it might take some experimenting.

I had that and the doctor put me on Levisin sl. You put it under your tongue. Works great for me. I can take one or two. Depends on how I feel.

Just a thought. Maybe you need a prescription to get you by. I am getting away from them. Slowly but I am. I hope this may help you.
