It sounds like your body is very toxic now not just due to the mercury, but also toxins that parasites and/or candida are releasing as they are being killed. Perhaps you need to add some more detoxifying herbs to your regimen? Perhaps licorice root, dandelion, alfalfa, or others? You did say you are using milk thisle which helps detoxification. So does garlic. Perhaps you may also need to drink more water. Are you getting enough potassium and sodium? In hot weather if you are sweating plenty you don't need just water, but also plenty of potassium. Potassium in present in large amounts in fruits and vegetables as well as milk and dairy products. While the typical American takes in too much sodium, those like me who typcally eat low sodium foods need to remember to use the salt shaker so they get enough sodium.
