This is embarassing to post about, but I hope some others have some expierence with this. I have been on thyroid medication for Hyperthyroidism for over 2 years. Every few months I will get a episode of very painful stomach craps, naussea and diarrhea in the middle of the night (anywhere from midnight to 2 am). I am fine the next day (a little unfortable with bloating) and don't experience another episode for a few more months. Anyone else had an experience like this?
