Taking Zymex II for Parasites

I just have a couple of questions. I have a hot feeling in my colon that gets even more hot after having a bowel movement (but it is still there even if I don't have a bowel movememnt). Someone on another forum told me that their colon hydrotherapist told them hot spots in the colon are a sign of parasites. That same person also said that once they killed of their tapeworm the hot feeling went away. I am going to get a series of 3 colonics but I am wondering will the colonic itself rid me of worms or would I have to do a product like Zymex to get rid of them? Also, I have been reading about multiple people who took Zymex having the "sleep coma" problems where they are aware of their surroundings but they can't open their eyes or move. Is that common when taking Zymex? It is really making me nervous to take that product. Thanks.
