Anyone else have issues with diarrhea two days after taking the shot? And how long does it usually last for you? I'm on 7.5 for nearly a year and still experiencing diarrhea lasting 2 to 3 days. This month I switched from shots in thigh or belly to my arm. Took my shot on Friday night--- today is Wednesday and still diarrhea persists. Thinking about quitting ,but my sugar is so much better I'm afraid to. Went from 12.8 to 6.4. A1C. No much weight lost...maybe 23 lbs in all that time. Would like to hear from others.
