Possible reaction to Align prebiotic + Probiotic

Last week I had a colonoscopy because of of a lifetime of urgent BM's, diarrhea, not able to nail down what foods are the problem. It is hard to maintain weight because and I remain thin. Here is a quote from the GI doctor - "I did obtain biopsies from your small bowel which have returned showing no underlying inflammation and no evidence of celiac disease. During the colonoscopy, I did obtain biopsies throughout the colon which have returned showing evidence of a microscopic colitis called collagenous colitis. This inflammation would explain your recent diarrhea. I am going to start you on a medication called budesonide to take 3 tablets once a day for 4 weeks, then 2 tablets once a day for 4 weeks, then 1 tablet once a day for 2 weeks."

I would like to ask this group if any experiences on an OTC product by Align--dual biotic--prebiotic + probiotic gummies. I began taking them at half the recommended amount (2 a day versus 4 a day) 5 days after my colonoscopy. My gut was staying calm so I was encouraged. Then, 7 days after colonoscopy at about 8:30PM my lower GI decided to empty out over the next two hours. That was bad enough but the odor had almost a chemical smell and even a intense sweet smell about it, ugh. I had C-def over 15 years ago and it made me think about that episode. After a couple of hours I took two Imodiums and things did settle down after that so I wondered if it could be possibly be due to the Align products.

I've been cautioned by my pulmonary doctor to be cautious taking corticosteoids as they weaken the immune system. I do have mycobacterium avium complex, bronchiectasis and Lichen planus.

Any insight would be appreciated.
