I am new to this board and have had a host of IBS symptoms (predominantly gas) for 14 years. It has become progressively worse and doing a search on the net about Dr. Pimentel's study eventually lead me to this site. I have done a search on the boards on Vivonex, but most of the threads were about people who were thinking about it or looking for more information. The only person who seems to have tried something like an elemental diet is skinny. And he tried a different brand for 10-12 days, I think and didnt feel any better.I am wondering if anyone has tried the entire Vivonex PLUS protocol for the 14-21 days or longer specifically for gas? Have you had any success? Did you try it alone or with antibiotic use concurrently?Thanks.
