Thank you for the answer, and I very much welcome the work that has been done on something that has not been, perhaps, recognised as being as important as it is. I know there have been previous questions, I think from Llyr Gruffydd and others, around this particular subject. I've had a number of representations to me, because although sleep apnoea and narcolepsy are particularly recognised, those represent only two out of 70 of the various sleep disorders that can have very significant effects on people's ability to work but also to live ordinary lives. One of the representations I've had is that Wales is the only country without a designated facility for the diagnosis and management of complex sleep disorders and that the level of service is a bit of a postcode lottery around Wales in terms of the way in which the services operate. I wonder if that's something that the Cabinet Secretary could look at in more detail and address, and I know that he will also have had particular medical representations on this issue as well.
