@pattycincinnat Hi, Patty
By any chance, have you discussed with your oncologist another option: to take half a dose of an AI or SERM until the colitis can be effectively treated? For me, half doses (to almost everuthing) seem to be effective without adverse effects. It's a thought.

Also, many patients have a good reaction to a probiotic called Saccharomyces boulardii regarding diarrhea. (So much better for your body than Immodium is.)

Hope all goes well for you in your new treatment plan.
