Might I suggest you seek the advice of a naturopath. I am sure that it has to do with your eating as well as other factors and a naturopaths approach I find is more toward finding the cause and then eliminating the cause and start rebuilding your health. It may seem like a long process however it is worth it. I found that a naturopath helped me regain my health. I did have parasites and with a change in my diet as well as incoporating a great cleansing program, drnatura's colonix, I have regained my health and well being. I continue to use the cleansing program each year to maintain my internal system. Good luck, I hope you find what will work for you. Keep us posted.
