I too was disappointed with the documentary,when it got half way through and they hadn't mentioned anything really about what causes it and that it is a neurological condition, (after all they interviewed doctors about it), I was so hoping the second half would cover it but I think the idea was to bring awareness of the condition and recognize that it is life changing for so many people. Now all we can hope is that a production company see these comments and the next documentary will cover what we are all desperately wanting to be put out there and we get the help and support that we deserve. No doubt if we could find a celebrity who suffers with RLS and would talk about it, things might move a bit quicker ??!!
