I personally had a different reaction to mercury. For some reason I cannot sleep in past 6 or 7 am, so I have to make sure to get to bed early, because even if I go to bed at 2 am I would still wake up at 6am and not be able to fall back asleep no matter what.

Thankfully now my sleep comes easier than it ever has in my entire life. I still wake up 1 or 2 times in the middle of the night but fall back asleep quickly. I also am able to take naps in the middle of the day, something I could never do my entire life. I suspect that in less than a year I will be able to sleep the entire night without waking if I continue chelation with ALA.
