I tried to edit my first post, but it said that it could no longer be edited. Anyway, I am a 5'7" male, so 150-160 pounds is a good weight for me. In other words, I never became underweight, but did go from being a good weight to being very overweight due to the mercury. It is amzing how fast most of the extra weight came off. Almost as fast as it came on when I first got sick years ago. Do you think I might have a chance of becoming underweight after months of chelation? BTW, a stone is 14 pounds. I did a Google search to look it up.
