hi corky.
my hubby has what is called Periodic Limb Movement Disorder.
its not rsl. it is repetaive movements of limbs or even facial musles after falling asleep. sometimes the movement can happen a 100x. stop and start all night long.
i just switched isp and don't have all my faves moved yet. i'll see ifi can find you a link and see if this fits your hubby.
