Hi Rosemary,
I've been following your story and I'm so sorry you're continuing to have such issues. I'm sure this is a stupid question, but have you ever tried taking miralax 2x a day regularly? I also had my colon removed... for colon inertia almost 4 years ago. The first 4 months were great, but then I just stopped going again. I had to use enemas and drink grape juice, but still never felt good. My next option was a bag, but someone suggested I try the miralax and it's been a miracle for me. My BM's are very liquidy, but I empty out and feel good.... I take it first thing in the morning and again after dinner. Not sure if it would help you, but at this point it would be worth a try if you haven't tried it yet.
