I made a special appointment with my primary care physician even though I was not due to see him for another few months. I made the appointment because I had an excessive amount of gas and bloating, and I was not sure what was going on. I had tried changing my diet a few times, but none of that seemed to help. When he told me that I needed to have a natural cleanse, I was not sure what he meant. I wanted to do some research before I did anything. He suggested I read about bowtrol, so that is the first one that I looked at. It is also the last one, because I had read so many great reviews on it.
