Thanks both of you for your replies, and gdawson I'm glad you are feeling better. It can be hard when you feel you are making little or no progress. That was why I stopped chelation a year ago. That was a mistake but at least I'm putting it right.

I'm going to be doing this for quite a while yet, and it's a real yo-yo. I was going slightly downhill day to day during my week off chelation, and yesterday I felt ready to start another round. It's been a shock to my system though. Hopefully in a day or two I will have adjusted. Based on how I've been reacting to chelation, I'm aiming for two-week rounds with a week's break in between. At least I've had those spells of feeling so much better, so I will not get discouraged again.

Part of this may well include having to get my diet back on track. It seems the hardest thing in the world sometimes. I had six weeks of a clean diet, of which I am very proud, and I cooked some great things from recipe books. Since that chocolate shop on holiday, though, I can't keep myself away from the stuff. When I started back on chelation I got an upset stomach and wasn't all that interested in food, so it was easy. Not so easy now. Chocolate is the devil's food, LOL.
