All I can think of is your water. If you have well water, do a test- your well may have been leached into, contaminated. I'm so sorry to hear you all are sick and going through this. Is there fracking near your area? I was reading up on distilled water - check it out, maybe it would help you all to buy some and try to detox? If you are eating a healthy diet, you will be getting vitamins and minerals from your food, so you don't need water to provide them. Keep us updated. Hugs to all of you.
