you know, I am on day 4...my only BM was loose, but that is too be expected with SWF (Salt-Water-Flush) or Colon Cleanse or senna teas. One almost CANNOT achieve a firm movement on this. If you read some of the more graphic posts, they talk about 'pee butt' (sorry)
One feels better after getting it out. I think most people are used to having really HARD bowel movement. My advice is to keep doing what you do. As long as you are not messing your pants, you should be ok.
I have never met anyone who did any of the senna or swf, or any internal cleanser for the kishkes to have hard stools.
Of course, I could be wrong. This is just my opinion and observation.
