It does seem that RLS is associated with foods, If I have a large meal, the RLS is worse, even tablets do not have any effect. Potatoes seem to be the worst. Cheese/chocolate seem ok. Coffee is an antagonist as well.
It took some time to get an accurate association with spuds, but even just a few eaten during the day seem to cause RLS at night. Only by eating very little of anything during the day, there seems to be no RLS.
I wondered if anybody else had this reaction?
