Strangely enough, I'm suffering from RLS by proxy.... yup, my hubby has sufered with this for years & whilst it doesn't even bother him as he's asleep when is leg is involuntarily doing an Irish jig, it drives me up the wall!! Especially as I am now the size of a walrus & even make walrus-eske grunts everytime I try & shift position, which means I'm only half asleep for most of the night!!
Joking apart though, I've heard that magnesium can be good for RLS but please don't take me word for it & double check with the midwife first.
