Hi
The sleep study was easy, the equipment is not obstructive and a night in the hospital is a break from the norm, they will put short pipes up your nose which sit just at the opening to the nostrils, on your finger their will be a heart rate monitor and this hooks up to small box on your chest fitted with an elasticated band, you should get a room to yourself as it is a sleep study, the equipment was not uncomfortable and i got to sleep ok, maybe take a tablet or a book and a non sugary snack plus a drink because for my study i had to be at the hospital for 1900 because reception amidnistration closes at 1930 and then the study lady came to my room at 2100, and then getting to sleep at my normal time then was 2300.
Look on the subject of sleeping with the mask and sharing a bed with a partner my wife laughed at first because it does look wierd, off course it does, but after night one it has become a normal thing for me to do every night. It took me about 2 nights to get used to the face mask mine is a full face mask, if you lay on your side you have to position your head at the far ends of your pillow so you don't move the mask off your mouth and nose, i have a Resmed S9 machine which auto adjusts the air pressure, it is very quiet, almost unoticeable.
And finally if you partner loves you when you are awake what difference does it make when you are asleep. I wouldn't worry too much the negatives is sleeping with a machine is unnatural the pros far outway the cons 10-1 with the likes of improved sleep, more energy, less moody, better circulation, less figiting in bed etc...
Good luck.
