What a difference a good night's sleep makes.

I'm slug-a-bed most of the time: at night I'm rarely fluffing the pillows before eleven; I wake up zonked, and more often than not stay that way all day as well. So a decent night's ZZZs is never going to be sniffed at.

I feel perky, bright, clear-headed, zoomed through the in-tray, and I don't have that bone sapping tiredness to drag through London either. Good, good, good...

Sleep is a hidden treasure. Worth the struggle.
