I am a nurse and work requires that I am in close bodyspace with patients and co-workers. On my work days I have only eat small green salads (no onions) and protein (meat & some hard cheese). No nuts, no milk, fruit, no flour, no rice, no potatoe----no carbohydrate except for a banana. This is hard to do (12 hr shifts) , but the gas that I would otherwise produce is too humiliating to "share".
I am, I think, on the far end of the spectrum. Most people can tolerate a greater variety without the gas. However, it is the luck of the draw. No one knows just how they body will respond post DS.
