I've been using ParaGone for 4 days and have found it to be very effective. I had an immediate reaction and expelled pieces of Tapeworms and what appears to be some worms on the second and third day, but all has been calm today. My stomach is flatter after and I also have greater energy, am sleeping better and overall feel calm and centered. I'm also eating a cleansing diet. I'd be interested to hear other's experiences with ParaGone. The instructions say to take for 15 days, go off of it for 5 days, then go back on for 15 days. Sounds like their are other parasite cleanses where you stay on the herbs continuously for months.
