I use a wonderful certified nutritionist. Her name is Michelle Burris ###-###-####. She is the best one I have ever found. She's been doing it for 20 yrs. She's the most knowledgeable person I know. She also can do all kinds of testing as well. She was able to help me where no one else was able to. I've been to all kinds of Drs., Naturopath and Homeopathic professionals and she has been the only one to be able to figure out what was wrong. Please feel free to call me any time. You don't want to use a regular Dr. with a nutrition program because they honestly don't have the training or experience that a good certified nutritionist has. I've been researching this stuff for years and have a lot of knowledge myself. It may be a little more expensive to go this route, but trust me, it will be much much cheaper in the long run and you will get to the root of the problem right away. What happens is you go the regular route and waste tons of money and lots of time and still don't have the answer. Also most of the tests that most doctors do are not conclusive enough. T.
