Hmm I get that same sensation and I just use the packs and do the Liver Flushes but not every 2 weeks, I go longer than that to recoup. I havent done any parasite cleansing yet, I have to admit I am nervous about trying anything I have read so far. I do admit it has done wonders for many people here, I am not doubting the outcome, I am nervous about living thru it lol
