Thanks again for the encouragement and info. It's in a form that I can understand and believe. Chelating has done me a lot of good so far, even with the GI issues. My head is clearer, and can think better, deal with people better, I'm no longer shy, and there are physical aspects too. It excites me to think I can proceed now and get even better, possibly better than I've ever been, or been in decades. It's a chance I want to take and so far, it look like things have gone as planned. I won't mind being alone and the age I am if my head is clear of depression.
