When I finally put it all together was about 14 monthes ago , after going from doctor to doctor for about 5 years health getting worse every year ,had dental work done by a regular dentist, after that visit my symtoms got worse and stayed that way for about 3-4 months ,that is when I knew that mercury had to be causing the problem , and been doing much better since having them removed ( the thing that really upset me was every time I would mention the possibility of mercury being the problem to the doctors ,they would look at me like I had three heads and discount it right away ( so just because they have a medical degree on the wall doesn't mean sh*t to me anymore.
