Just when you thought things couldn't get any worse!
I checked out the NHS UK website a few days ago and was shocked to learn that RLS sufferers are more likely to to have heart attacks and strokes than non-sufferers. It went on discuss cholesterol and BMI. I was further shocked to learn that at 5'4" in height and weighing 10.5 stone, I need to lose 1.5 stone in weight. It suggested walking 10K steps per day. I have started walking a mile in the fresh air each day for the past two days and have slept better. The website has lots of information on weight loss and dietary tips.
Hope this helps.
