Hi Flyr, welcome to HealingWell!
You cannot OD on good bacteria. In fact, I read on the UC (or maybe Crohn's board, can't remember which) that a woman takes about
500 billion a day to keep her disease under control. I have also read that it takes about
3 months of continual use to see results in the digestive system of someone who is battling yeast, c. diff., etc. Most of us on this board take it everyday and don't plan on stopping. My doc said I won't need it forever, but that I can continue or stop as I see fit.
