A birdy with a yellow bill, hopped upon my window sill. Cocked its shining eye and said. 'Ain't you shamed you sleepy head. So asked Robert Louis Stevenson in Time to Rise. Am I ashamed of an inability to wake? Am I ashamed of being a sleepy head? No. Frustrated, exhausted and frankly totally p*ssed off, but not ashamed. Being ashamed of pathology is kind of pointless. Sleep apnea may be part of the problem but even my sleep physician thinks the numbers don't reflect the level of exhaustion. The second most likely cause is depression. That would explain a lot. Of course many people will say, go to bed earlier... or drop the afternoon naps. If only it was that simple. No-one who is not a shift worker or a teenager chooses to go to bed at 2am. Bloody annoying is my official diagnosis. So birdy, mind your own business. I saw you bullying just about every other avian species at South Bank this afternoon. Who are you to lecture me?
