I've just joined your forum today after going through the initial diagnosis for OSA this week.
I'm a 47 year old male from Sydney Australia, and am currently trialling a ResMed AutoSense machine. Not sure of the brand of mask I have, but it is a full face mask.
I've been using the machine since Tuesday, first night was brilliant, had a couple of not so good nights since. I'm putting this down to getting used to the mask, and a dental issue I've been putting up with. Had the tooth pulled this morning, so looking forward to further improvements in the near future.
Anyway, looks like I have plenty of reading to do to get myself up to speed with this whole new stage in my life.
