Hi there! Your nauseous feeling might be the toxins moving around...people sometimes do feel icky for a few days when they start to cleanse. Someone else might have some other information, however! I'm curious...how long have you been taking the B&P and how many times a day? Are you taking a seperate parasite cleanse/killer program at the same time, or are you getting parasites out just with the B&P?? Most curious. Yes I am! Were you getting parasites out when you were feeling nauseous? Could be the die-off of the parasite that made you ill...hmmm! It sounds like you're feeling better now, though? And continuing with the B&P? Wow, you must feel great having gotten out so much plaque AND parasites! Good going!
