Thank you for your comments. Since "failing" my first EBRT radiation simulation last week, I've been following a low fiber low gas-creating diet. It seems to have lessened what little gas I had but it's not ideal for bowel movements. Trying my best to solve these situations. Taking Gas-X and eating/ drinking things recommended by the FODMAP plan. Will I have to continue this stuff when my 28 radiation sessions begin? Looks that way.
