Another promising probiotic is SLV#3 my gastroenterologist suggested I try it after years of telling me that all probiotics were the same - just get one with 3 strains. I looked it up on the National Institute of Health website and was totally amazed at the potential benefits as compared to the over-the-counter products (This one has to be kept refrigerated so it won't be on the shelf so ask your pharmacist if he can order if he doesn't have it in his fridge.) It's a little pricey but I'll try anything to tame the storm raging in my gut.
