Well hopefully they get this figured out for you. The timing of your news is interesting as I actually just came from my GI and he suggested starting me on flagyl. I don't think overgrowth is my issues and honestly think I have another intestinal hernia.
Last night and today have been been miserable as I was up every hour pooping and I am extremely weak/fatigued. He thinks it could be overgrowth but I actually feel less bloaty than I did a month ago. The reason I don't think it bacterial overgrowth for me is that you had such constipation issues and my issues are cramping diarrhea with a loss of 6 pounds last night.
