I had done a Meridian BioFeedback test over 2 years ago and it came back with tapeworms. So I have been fighting them since. Praziquantel and luguls Iodine does work but consistency is the key with any treatment. Also switching treatments since they seem to aclimate (sp) to what I am doing and build up resistance. I am now back on Praziquantel since I have one behind my left eye again....I hate these blasted things!!!
