believe me I understand I am giving you a lot of info here that may seem overwhelming, but mercury could be one possible reason that doing all this cleansing is stirring up metals in your body and making you feel worse.
Unless you eat a ton of seaweed the likelihood that you are Iodine sufficient in your tissues is about zero. We are being bombarded with too much bromide, fluoride and chloride to stay Iodine sufficient.
Once again I am a fan of testing. I realize the inherent limitations of tests, but there is also the potential of them giving useful information. There is an Iodine loading test and also a bromide level test that you also might consider. These days I am less interested in the iodine loading test because everyone is low anyway. Although sometimes it can give info that implies an iodine transport problem. I am much more a fan of checking ones bromide level as a baseline before starting iodine and then rechecking every 6 months or so. I am mostly a fan of this bromide test because if people don't see a noticeable change in how they feel right away in a month or two they stop taking iodine.....while it may take several years to kick out the bromide from your body and thus take awhile before you notice any changes. Iodine is a long-haul nutrient.....some people notice changes right away, other notice changes over time.

do you have silver fillings?
again sorry if I am dumping a lot on you all at once, I am just pretty passionate to see people get well.
