Calif123, You are absolutely right. What may work for one person may not work for others. And, "medicine is based on facts not beliefs", I agree with you on that point also. But, my the intent of my posting was to let others (who may not be clear on this) 1) to know what Questran is actually for (fact) and 2) why its side effect profile (fact) may actually help them in their quest for a remedy. There have been posters who are under the "belief" that if they don't have gallbladder/bile problems this won't help them; and, possibly, it may not. But they shouldn't be discouraged, based on one docs opinion, from trying just one more remedy. There are many here who have tried many solutions, and have still not found one thing which works for them. And, I agree with you on the point that, If it hasn't worked within a month's time; even after adjusting the dose up, then it probably won't. You are absoutely right! What we need to remember, is that we are all here for pretty much the same reasons; we need help and for many of us; this is our ONLY help. I have been through more docs and more meds than you can imagine and it was ONLY THROUGH THIS BOARD,that I found what works for me. NONE of my docs ever suggested Questran; not one! It was ONLY through this board that I even heard of Questran and for me; it's saved my life! Same goes for the calcium treatment which has helped so many others. When I told my doc about it; he poo-pooed (no pun intended) the idea as nonsense. he "never heard of such a thing and blah, blah, blah." and in a strict scientific sense he is right. Technically, and based on "medical facts and not beliefs", calcium in these quantities is used mostly by women for the prevention of osteoporosis. BUT, it is being used, with success, by many here, primarily for its "side-effect" profile and that is constipation. And they have found relief with this remedy, regardless of the lack of scientific data supporting this fact. Xanax worked for you to help control this condition, but you will not find IBS-D listed on the package insert as one of the "Indications" for which it was developed or should be prescribed. Many drugs are prescribed and used, as I said, "off-label" for uses other than their original development. I am not "pushing" Questran; I will not benefit in any way whether someone uses it or not. I am perhaps overly excited because it did work for me and I've seen through this board that it did work for others; and being a fellow sufferer just want to pass along a remedy which just MAY change someone's life. Therefore, I would not want to see anyone discouraged from trying a possible remedy because they think it will NOT work simply because it was not originally intended for use in this disorder. I would always suggest that someone try something more accessible and non-prescription first, like calcium. No, I am not a doctor either~but, thank god for me that I found this "non-doc" board for suggestions, for had I relied soley on doctor's solutions, I'd still be suffering from this debilitating condition. I did review my original post, and although I was not angry, perhaps I was little more "emphatic" in my language than I had intended. My intention was to inform and not to insult. Thanks for the interesting discourse. Hope you have a Happy Holiday!
