Thanks North. I actually am familiar with methylation issues and just took the 23andme MTHFR test. I'm currently awaiting results of that. I just wonder if I picked up a parasite living in Germany and then possibly an additional one from my husband's time in Iraq. I have had candida for forever, but never had major allergy or heart palp issues from it. All of the allergy and heart palps are a relatively new thing.
