Hi Sally I am having the same problems and was finally sent for testing, it was found I have gastroparesis. I was put on to a med called domperidone. It help with mobility through the stomach and bowels. it has given my some relief, might be worth looking into this med for you. My doctor has me on MiraLAX which doesn't always work and I have been struggling for answers myself. Most of the meds I have tried ether cause terrible diarrhea or don't work at all. I find if I don't cleanse at least once a week I start to back up which cause a whole host of other problems. The go to med for me is called "Constella" I am in Canada so the name for the states might be LINZESS. I struggle to find a middle ground with this problem, maybe this post might bring other will similar people issues with more options.

Best of luck to both of us
