HI Lena......glad to hear that you get bloated with anything too. I'm on my second round of Prednisone....also taking Pentasa and Aza, like you.
I put myself on a liquid diet as of yesterday for two of my meals, and eating very lightly for the third. Although I am pooping more, and more often, my tummy doesn't feel as bloated and I am not so uncomfortable and crampy. Nothing I have done since March of this year has helped much at all, so as much as I enjoy eating, I am really gong to give this my best try to see if it calms my tummy down.
