Pouch Test?
The 5 day pouch test was created by someone ..not sure if they have a specialty in the medical field or what but it is suppose to allow a post op person to "de carb" themselves while getting back in touch with the tight feeling of being full.
Here is one of the websites that explains it. I think it is suggested for those one year out or more.
