I agree with Alex that the first two weeks are the toughest. A couple of friends joined me on the cleanse phase after I had already started it. One folded on her day 3, the other on her day 10. I don’t know if day3girl has yeast issues (most people do, at some level, but I think she was just detoxing after a vacation and wanted solidarity), but day10girl does, although not severe enough for her to get back on the wagon, apparently.
For myself, I was starting to feel some good results by day 9 or 10, in terms of far less brain fog, less fatigue, and my cravings were gone.
Keep it up! 🙂
