Agree with westernmom, yes I have tried all of the above. Even putting camphor under the sheet at bottom of bed, having brandy and hot milk, putting legs up on pillow, lavender in bottom of bed, take magnesium, swiss sleep pills and so far no luck.
The worst thing is that you can go for a week and no problems then you have them each night then miss again. There does not appear to have any specific thing that I can find that triggers it. I lay there till 3 or 4 in the morning and dont go to bed till 12 or later some nights the shorten the time tossing and turning. It is so frustrating especially when your partner sleeps through it all. Good article though and should hopefully help someone.
