Soap etc didn't work for my RLS, but drinking 6-8 ounces of tonic water does work. May have read it on EC but been doing it so long I forget. I buy diet tonic water with "real quinine" listed in the ingredients. Good luck and sleep tight!
RLS: I drink tonic water with quinine. I have never found it without quinine. I like it so I sip on it all day and into the evening. If I'm not home all day, I sip on it all evening. My doctor suggested 12 oz. in the evening. That amount worked initially but sipping on it all evening is a must now. Every once in a while it will act up despite the tonic water. I don't just have the creepy crawlies that make me need to stretch my legs with no relief. I also have uncontrollable movement of one or both of my legs. I used to have it in my arms also. They would flail on their own during the night. Jerking up. Typically the left arm. When it acts up I chug the tonic water. Glass after glass. On the rare occasion it takes longer to take effect.
