During a recent holiday abroad i had a really bad re-occurrence of rls. I have not had rls for many years (i now have plmd). I thought long and hard about what could be the cause of this problem, i then started looking at the change of diet while away and realised my potassium intake was much lower than normal. As soon as i returned i went to the local pharmacist and got some potassium supplements and started eating some bananas. Hay presto! No RLS just back to the plmd. Has anyone else tried this?
