Susan, I don't have it terribly, but water helps me as well. On days I haven't had enough water to drink, I can predict having an issue once I go to bed.
Electrolytes (like some of the supplements mentioned here) help when I need to "catch up". Usually, a tall glass of H2O once symptoms start for me will fix the issue in 30 minutes or so.
I'm not a doctor nor have I seen a doc about RLS, but that's what consistently works for me.
