I am about to move back to a community that fluoridates the water. Ugh. I lived there for 23 years, and my dog and I both suffered from hypothyroidism. After moving to a community that does not add fluoride to the water, we are both off of our thyroid medicine. Now we're moving back, and I'm trying to figure out what I should do about the water situation. All of the options seem so expensive. Penta is great, but who can afford that, and I'm not really sure about all the reverse osmosis and distillation systems. Does anybody have any affordable advice to offer me?
