Hi Mikey,

Brilliant detective work on your part, well done. Yes I've seen a few sites myself recently that said that lack of calcium can cause insomnia. I've been supplementing with calcium citrate for a year and a half though, so I don't think that's my problem. When I started all the supplements I hoped I'd be lucky enough to find that my problems were due to a simple deficiency in some nutrient, but I think in my case it's more complicated than that. Thanks though. BTW does your wife take magnesium as well? The body needs it for calcium absorption; otherwise the extra calcium just floats around and goes where it's not wanted, such as in plaques in the arteries.
