Yesterday I listened to Professor Colin Espie lecture on "What is sleep ... and why does it matter?".   I then went on to his packed two hour workshop on "Assessing and treating insomnia in everyday clinical practice".  I've heard Colin lecture before and been to a full day workshop with him as well, but it's great to get an update on where sleep research & treatment has got to.  Colin is a professor of Sleep Medicine linked with the Oxford 'Sleep & Circadian Neuroscience Institute' and is very much a world expert in this area.
