I would just like to tell other sufferers of rls of my recent discovery and massive relief of rls after at least 30 years of suffering. I have for some time been taking a daily iron tablet also a small glass of tonic (containing quinine) before bedtime but I have also recently added to the iron with a nightly portion of spinach washed and cooked slowly with no added water. My rls is 90 per cent better. It's a hassle cooking spinach every night but well worth it. P.s. I have an allotment and grow my own. But not as tasty as the baby leaves bought in most supermarkets.
