i really think he is trying to rip you off. everyone claims to have the answers. you can find the answer or "most" of the answers yourself by using this BB, reading the "lay" books, doing your own research, using common sense, using detective skills, focusing on the problem, and then once you have it narrowed down -- attack it.IBS or malfunctioning digestive disorders are due to a variety of causes. your cause may be different than the man who is trying to sell you something.you might just have "small bowel bacterial overgrowth", or fructose intolerance, or any number of things. you need to narrow it down. ex. does it improve when you go on a zero sugar, low carb diet? what proteins make it worse? what role does stress have? (in my case i will experience the condition regardless of my stress levels -- it is due to food allergies/intolerances)save your money and do your work/research
