Thanks Imgeha. That's a good back-up plan if I can't get this sorted in the short term. Upon waking at 3 am I think I'd be willing to try a small dose of melatonin. What I figure happens, is that the melatonin is released too early and it runs out in the middle of the night, leaving me wide awake.

I'm hoping that I can use the sleep problems as a natural radar to show how the chelation is going, and taking something right now might make that impossible. Then again if I am jetlagged all the time, it will be impossible to do much else in the day. I just wish there were more info and studies available on melatonin. It's another one of those not-so-well-understood things that our doctors know nothing about.
