My legs can't rest when I'm in withdrawal unless I has Zanax or some other sedative.  It normally lasts for 12 hours followed by very lethargic feelings that persist until I get Oxycontin or Methadone.  At one occasion I was 9 days without anything but accepted drugs, which prolonged the dependency.  This is the repeated theme of my life over the past 12+ Years.  I'm afraid there's no outlet.
