I was lucky and had minimal RLS through my w/d's, but from the advice I've seen here, eat lots of bananas, apply a heating pad to your legs,hot baths, and this sounds crazy, but many on here swear by it...place a bar or 2 of ivory soap in your bed sheets
by your legs.
The forum is quiet right now, but I'm sure you'll get a lot of advice come morning.
Congrats on day 3! You've gone through the worst of the physical withdrawals!
