Hi Janaki...well, a few people over on the parasite forum had strange 'cotton ball' things and eventually they found a picture of what they had gotten out!
The posts within that link regarding constipation and b&p should help you decide whether you want to attempt it again. It may have been your water intake wasn't enough...eating fruits and vegetables helps instead of mucoid-forming foods (milk, bread, meat).
There will be some good way that you can clean your bowel - you just have to find that way.
In the article "journey to..." he suggests a solid 2 months of bowel cleaning. That sounds like an excellent idea. 2 months out of your life? It's very little. Then just maintenance cleanses a couple times a year.
