I've suffered intermittent RLS for years, and it was at it's worst when I was pregnant. I thought perhaps my hormonal changes had something to do with it. Lately I haven't had a single attack for weeks, and pondering over this I have noticed a correlation between my digestive system and my RLS. Namely, I get attacks if I am constipated. Throughout my pregnancy I was chronically constipated. Now I think that was the cause of my severe RLS episodes, which would have me unable to even sit in the back of a car for five minutes without kicking the front passenger. Has anyone else noticed a link like this? Would you maybe test it out?
