Is there anyone out there who can eat pretty much everything one day and not be bothered, but try the same foods a day or two or a week later, and have D all the next day? I find this happens to me a lot, so aside from really rich, and fried foods and fast-foods (which bothered me before I developed IBS), I can't pinpoint anything specific. For example I can eat a banana and it can send me into spasms within a 1/2 hr., and the next day I can do the same and nothing happens. How do you determine what is really a no-no? I have been using the CVS calcium D (purple box) and have had no D for the past 6 days. I'm knocking on wood!!!!
