Hi megan'
I know this post is a while back, but I wanted to say that when I experience these digestive problems like you describe it is because I haven't added enough greens and distilled water to my diet.
I find I have to keep account of just what I am eating and druinking. When doing the cleanses sometimes eating right is something I have to concentrate on.
Basically I do a lot of juices, but find that I also need the greens and the bulk they provide in the intestine and sometimes don't eat enough of them making my intestines a little dry.
Hope this helps.
