I be constipated too. Part of that is because I am always on antibiotics, but I remember the very early days before antibiotics and I tended toward constipation. The sad and unfortunate fact is that I often have to use an enema to completely empty my pouch. If I don’t, I just keep going, pass a little stool, do it again - over and over. I get no sleep, my stomach site hurts and I am miserable.
I hope you find someone to help.
