My doc just recommended it to me. He did not realize I had already started taking it (tho like you I ran out and have to get some more, but I am not backsliding even after 2-3 weeks off it). What is working extra well for me are the cultured veggies, and I DID backslide when I went off them for a week. But, when I went back on them I got lots of die off after 2 days of eating them again - I was surprised candida had come back after being off them only a week. But, they are POWERFUL!!
