Slightly off topic, but after some ghastly nights last week with symptoms that don't need to be described, I thought it might be an idea to get a new bed. My current one is at least thirty years old, and although of good quality is about twenty years older than the ten years a bed is supposed to last according to the experts (who all probably want to sell beds).
So I did a quick search for beds which are good for back pain (which I've got in addition to rsl), and ordered a Danish-built bed which topped at least one back-friendly bed list. It's a normal, non-adjustable bed (and it's on sale at the mo, too).
But what I was really wondering was whether anyone has any experience of adjustable beds, and whether they might help with at least some of the rls symptoms. Personally, I see no reason why raising the bottom of the bed would make any difference, but you never know.
