Microscopic colitis

Hi, wondering if anybody here has this for a dx. I have been having a flare for about two months, it is getting a little better with the meds but the doctor wants me to go on a short dose of steriods. I already have a muscle disease so hate to go the steriod route, (plus do not need to gain weight) lol. But if anyone has any hints for me I would appreciate it on how to control this. It is the longest flare I have had.
