they basically said to do a full one for the first 1-2 weeks and then for maintenance if you need 2-3 times a week during the candida diet.
For me, I did 2 weeks before the cleanse, and then I felt really good and didn't use it at all for 2 weeks after, but then I ate hemp seeds (not sprouted) and I didn't feel very good after that, so I fixed that with the Oxy.
Right now, I do it before I do a cleanse, or just 2-3 days every 3-4 months, depends how I feel. since I healed I allowed myself to eat bad foods once in a while :-)
