You're not crazy for thinking your fillings might be making you ill. Those who are crazy are those who think placing the second most toxic material on the planet in our mouths won't have health repercussions. Even if they didn't leak (and they do), at the time of insertion, there would have been high exposure. Also, every time the filling is worked on. Also if removed and replaced with another one.

Just make sure you get a dentist who uses ALL precautions and that you take it at a pace your body can cope with. I've suffered immensely with many things for years, and finally know I have the answer, even though most people don't really believe me.
