Prior to getting rid of the greatest mercury problems, upper and lower right teeth; I was getting sluggish by 3-4 p.m. I have always been known for my limitless energy and never felt “tired” during the day – until the last several years. Further, I had trouble sleeping when I did go to bed, regardless of the time. There was a “taste” of metal in my mouth. After the initial replacement my energy level increased dramatically. There is now no metallic taste at all and I am sleeping well whether I go to bed early or late. I seldom fall asleep during movies or theater performances anymore. I know I still have a ways to go, but I am thrilled with my progress.
