phsyllium and blackstrap molasses cleanse

I have just started a Phsyllium and blackstrap molasses cleanse and was wondering if anyone else has tried this one. I started on Friday and by Sunday I had uped the dose because I felt really constipated and my lower back really hurt. I have been drinking tons of water. I feel a lot better, but I now have a stiff neck and my whole back is sore. I usually have been having about 6 bowel movements a day now. Two are always easy and the other ones feel as if I am totally constipated. I have noticed my stomach looks smaller, but the scale says I have gained 5 lbs. Not sure if this is because of all the water I have been eating well. This is my first cleanse and I am not sure when to expect the big stuff. I will just have to wait and see.

I am wondering if anyone else has had similar symptoms with this type of cleanse or with any cleanse.
