I use something that might help those who are having trouble sleeping. It's called “Sleep Minerals IIâ€. I don't normally advocate “natural†products for sleeplessness, because I've never found anything that would help me, unless it was a prescribed drug, but these capsules are just basically calcium and magnesium with a few other things thrown in, but there is something about the way they are formulated that really seems to make them work. I was really sceptical when got mine, but after using them for a while I really think they do help.
I've had a big improvement with my insomnia since I got my progesterone intolerance under control, so I'm not sure if they would help if your insomnia is the full-blown hormonal type that only drugs help, but if I wake during the night or have trouble getting to sleep, I take one of these capsules and I fall asleep straight away, without fail.
They're not expensive, and they might help some of you. They do say that the longer you use them the better they work, so if you don't find they help straight away don't give up. At least try them for a couple of weeks before you make up your mind.
