Hi, my digestive issues cropped up two days after initial treatment. I had diarrhea and I treated it with Imodium, but then I was constipated for two days. I also took a Zofran for nausea, and not sure if that drug affected my system. Also had two bouts of heartburn in the ten days since the treatment. Doctor put me on Omeprazole. Trying to eat small portions more often, and that helps.
