Hmmm....just one dose made you that constipated? This is what I've noticed, it seems no matter what cleanse people do, at first you will get constipated. This is at least what happened with me. I started out with CleanseSmart and FiberSmart and for the first few days I was miserable and not very happy but I stuck with it and things started working better and I ended up having 2-6 movements a day. On the CleanseSmart I only noticed rubbery-like mucous but nothing hard or like the pictures. Plus some of my BM's were small and mushy and sometimes I had terrible belly aches where I had to run to the bathroom. Overall I liked CleanseSmart but to continue with my cleanse I chose to do the BP's next. I've been on them for 25 days now and absolutely LOVE them. They are working really well for me and I must admit I was skeptical like you and was actually a little worried to try it because of some people's results. I only take 2 doses a day since 3 does constipate me. I started out on the first day with one dose, then I increased it to 2 for about a week, then added the 3rd and couldn't last more than 2 days so I went back to 2 and I am getting lots of mucoid plaque! Well whatever you decide I hope it works for you. Good luck.
