Day 15, feeling fine except for a pervading weakness... If I were not at liberty to rest in a peaceful environment, this would not work for me. Which, of course, is what is recommended for water fasting.
At Day 10 I had the clear feeling I was not finished, and so have continued. I pretty much have Thursday, Day 17, as a goal and am feeling much more like I am finished with this cleanse, about ready for the break although I still have no desire for food.
