I tried 3-4 before finding one that works for me too, but unfortunately I didn't keep track of all of the failures' names. Looking through my rough notes and gmail, I found Now Foods Probiotic-10 and Ethical Nutrients Inner Health Plus. The one that ultimately did the job was California Gold Nutrition's LactoBif, which you can buy on iHerb and has a surprisingly large volume of positive reviews on the site. I started with the 5B CFU and ramped up to the 30B. Hope that it does something for you as well!
