you dont have to take it daily. what i did for a month was just what felt right. it was really wierd because after about a month of doing that i didnt have any of the digestion issues that i had post cleanse. like bloating or everything feeling like a rock in my guts. so i stopped eating the yogurt. im still fine and normal.
the pills that you buy have direction on how you take them.
basically you are just setting up a colony in your intestines again. and then the colony will take over from there. you dont need to keep adding to the colony.
unless:
-you do another bowel cleanse
-take anti-biotics.
