I recently got my 1st class medical (for the first time in 10 years) but received a SI that is asking me to provide proof of 12 months usage, using the CPAP 75% of the time, and for an average of 6hrs. I've only been using the CPAP for a few months and that has been sporadic, mainly because I can't stand the thing, and I also spend time between two homes, so it is tough transporting it all the time.

Question is, if I submit the info, even though it won't show that I'm using it up to the required standards, what will happen?

Also, a family member is a dentist who can just do a dental appliance and then give me a sleep test. Would this be a better route?
