Me too...I'm struggling at the moment actually. My job is, well, let's say it's all-encompassing and has a voracious appetite, and I sometimes struggle to detach enough to find a restful sleep...often up at 2:30 and start to think and that's the end of sleep for the night. It's a problem.
I'll try cheetahs in tuxedos and ballgown attired giraffes and see how it works.
