It IS early days for you in your CPAP treatment, but it's important to feel secure in what you're doing.
Manyzzzs and Nuneatonman 37 have given you good advice, and I'd just like to say that your apnoeas should start to drop if your machine is doing what it's supposed to do, and you are wearing your mask every time you go to sleep. (Yes every time you go to sleep, not every time you go to bed ... so that means 40 winks on the settee after a good meal too!)
If things don't seem to be dropping as regards the apnoea numbers in a month, go back to your sleep clinic and get them to check your machine and your mask fit. Or if you feel that it's something you don't want to leave so long, contact them NOW.
Only they are medically qualified to interpret your results and compare them to your baseline results and then alter your machine if necessary.
But CPAP is not a 'one-size-fits-all' therapy. You need to have a dialogue with your clinic/technician, and, rather like with a newborn baby, until you get used to your new lifestyle, don't hesitate to contact them for help as often as you feel you need to.
Do keep us posted, and all the very best. x
