I'm glad that helped, Diane. I really hit the rocks when I stopped DMSA. What really clued me up was the fact that if I took a DMSA cap when I woke in the middle of the night, it got me back to sleep. Otherwise I'd be lying there with my heart pounding. That's a sign of low cortisol. The DMSA was making my adrenals work hard. It provided substantial relief, but I was heading for a massive crash. As it is, there are already a lot of pieces to pick up.

Bex, thanks for the hint about cavitations. I wouldn't have any though, thankfully, because I've got all my teeth. I keep hoping that if I carry on researching, eventually I'll stumble across something. At the moment I'm thinking that I need to get my ferritin up so that I can treat my thyroid; but if my GP won't help me with that (they tend to think that ferritin isn't important unless your haemoglobin is also low), it's probably going to take months of supplementation before I can get the levels up myself. I might give Dr. Peatfield a call and ask him if he has any ideas.
