I have had weeks, now, of sudden D, after feeling pretty good on the calcium and Elavil for some time. I can't work out why this IBS returned with a vengence as my lovely quiet life hasn't changed - no stress at all. My doctor has stopped the Elavil and prescribed 3 tablets of Librax a day, Calcium tablets, plus a powder called Smecta (a French medicine to bathe and soothe the gut - my guess it is like kaolin). This has not made any difference to the diarrhoea episodes and after a desperate dash for the toilet in our local supermarket today, I came home in floods of tears. This is really ruining my life and is very depressing. I am not depressive, just very depressed about my condition! What makes it even harder is that almost NO stores in France have toilets!!!Has anyone had any experience of taking Librax? How long should it take to start to work? Should I be patient and wait for it to start to work? I have given up sugars, caffeine, colas, orange juice, take Benefibre daily and eat oatmeal for breakfast. I don't eat fatty foods, never buy ready-made meals or junk foods. I am lactose intollerant and am very careful not to eat any foods that contain this, so this isn't the problem. My doctor said that I should try Librax for a month, and if no change, he will send me to the hospital for the pill swallowing camera test (which although I dread, I am desperate enough to do it!)Any help/suggestions would be so much appreciated,
