<<Disclaimer: Verify this information before applying it to your situation.>> Well folks thanks SO much for the helpful responses, but I must say I am more overwhelmed than before. It seems most peoples responses were based on the first-hand experience of either themselves or a family member. The responses on how long to try GF if medical tests rule out Celiac range from one week to 3 years! THREE years!? All on a total whim, a guess that *maybe* a gluten-free diet might make one feel better even though biopsies were negative! Wow! That sounds almost ridiculously long. But I guess with health nothing is clear-cut, so I guess I (and my friend) will give GF (and DairyFree) a go for about a month just to see. After a month, if GF isn't helping me, I'm not sure what I will do. I may be moving from California to New York in a few months. A major change and huge upheaval - quitting job and finding apartment and all that. I'm not sure how well trying to manage a gluten-free diet will fit into that experience. Actually I *do* know - it would be quit awful, judging from the past "special diets" I have tried. I think the timing would be awful. So maybe I'll do GF here for a month or so, then - if it ISN'T helping - I'll return to an easier, more normal diet during my move, and once I'm settled in my new location, then I'll consider doing GF for longer, maybe a few months. Does THAT sound reasonable? What would YOU do? I don't think 3 years on a gluten-free diet with NO IMPROVEMENT IN HEALTH is really ever in the cards for me. Patrick
