Hey Jeff- your symptoms sound similar to mine. Constant "flip flopping" is what I call it, when I eat, when I don't eat, all the time. And towards the end of the day, after I've eaten my multiple small meals throughout the day, I get this discomfort in the lower left part of my abdomen that is just indescribable... I feel so full and uncomfortable no matter what I eat. I was dx with abdominal adhesions which were causing bowel obstructions back in December and the surgeon said once they removed the adhesions my symptoms would get better- didn't happen. I am now 5 weeks post surgery and the symptoms are back. They are going to test me for SIBO and maybe do an emptying scan. One thing that did help with the "flip flopping " was bentyl which is a smooth muscle relaxer.
