No a Gastrologist prescribe the medication. My odor is not gone. I still smell it like before I go to the bathroom. It is really loud. This nasty bug is tough. But, I will defeat it one day. Sometimes, I can still smell the odor with certain foods. I'm dissappointed with this antibiotics doc gave me. I think it made my odor worse, I was taking probiotic. I probably needs a stronger probiotic with the 38 different strands of bacteria. I'm going to purchase it soon. I hope the antiobic works best for you. My doctor prescribe me a Mild antibiotics. I'm so angry. These bacteria are no joke or to be played with. I will ask doc for a stronger antibiotic, not the generic brand.
