Agree on Calcium as top sleep aid. I believe I've tried it all, including medications, but especially nutrition.
It seems obvious now, but I'd always tried calcium with other supplements.
I've gone so long with this deficiency, that I need calcium chelate without co-factors. It's something genetic because family members had other signs, such as heart arrhythmias, anxiety, so on. I'm taking a lot so I think it's an individualized thing.
A well known Homoeopathic doctor once told me that during sleep the blood leaches calcium from the bones and that taking an alfalfa tablet at night is a good way to take calcium in. (If burned in the field, the ash from an alfalfa crop tests 90% calcium.)
Importantly, being easily absorbed, it doesn't leave deposits in the joints. I've found that for me a low dose is best, the higher strength caused constipation.
I have no problem getting to sleep, but for the last couple of years I keep waking up after 5 or 6 hours of sleep and then can't get back to sleep. I've tried everything but nothing worked. I think I've discovered the solution to this problem. I always take my calcium supplement at night because it seemed to help me get to sleep. Recently, once again, I was up at 3:00 in the morning and couldn't get back to sleep. As I lay there frustrated with my inability to get a full night's sleep, I thought about how my low dose calcium supplement seems to help me get to sleep so I got up and took another supplement at 3:30 a.m.
I took the pill and started reading my book (with a book light) and after about 15 minutes, I couldn't keep my eyes open. I slept until 7:15 that morning. I now keep my calcium supplements and a glass of water beside my bed. I can't believe something this simple has cured my early morning waking.
