I know what you mean about sleeping in unfamiliar surroundings. I'm another cat, like you. I'm hopeless sleeping on planes or other people's sofa beds or hospital beds. I like my own bed and my array of pillows, strategically placed to support my back and shoulders. Many of my friends will attest to my attachment to pillows - I'm known as the pillow lady. I try to take as many of them with me as I can when I am staying away from home - even managed to get a few in my suitcase when we went to San Francisco recently! Being comfortable in bed makes a huge difference to good quality sleep.

Fortunately for me I've never had to have a sleep study - must be awful. Rob has had one and he says they are not exactly sleep-inducing. Still if it achieves something in the end, it will be worth it. Good luck! I'll be thinking of you, Kat.
