Hi Lorna
I have Sleep apnoea, I was given a small watch sized machine that I wore for two nights. I then returned it to the hospital and was given a cpap machine. I know I look kind of odd sleeping with the mask on, but I had no idea how tired I was until I got my first nights sleep with the machine, now there is no way I will sleep without it. I am no longer falling asleep in front of the tv or in the middle of a conversation, or even at my desk (happened twice, boy was I red faced!!!!!). Good luck
Lorraine
