When did you take your last enema. You might have something in your colon that's irritating. The reason for the enema is, since the colon doesn't move during the fast, to move toxins out. I know, we don't want to do those things to often. but in the case of feeling unwell, I'd even do 2 per day until it subsides. A very mild one is 1 cup of camomile tea with 1 quart or more water with 10 or so drops of lemon. Hold it in for 15 min.. Maybe you have a lot of stuff still lodged in your colon and as you fast it gets released, causing your discomfort.
Maybe it'll pass by itself though.
Feel free to ask, if you need any tips. You know where to find me.
