Hi Lazar,
I'm 59 (for a couple more days, anyway

) and I've been using this treatment a little over a year now. Absolutely using it - for every sleeping moment, including even the shortest naps. I know it's
that important even though I've got it mild, compared to so many other people. The fact that I had almost immediate relief from all daytime sleepiness helped convince me, despite starting out with a less than ideal machine/mask (an old borrowed straight cpap and a leaky gel mask.) The message boards are a wonderful place to get help, hints, suggestions.
As for using it the rest of my life...I'm quite content with that idea. Sure, I'd rather be able to just lie down at night and go to sleep without going through all this rigmarole - who wouldn't? But the nice thing is - I can take it off in the morning and go about the business of living. For all its nightly inconveniences I look at a lifetime of using my autopap as a
much better prospect than having a massive stroke land me in a wheel chair or a nursing home for the rest of my life. I can greatly lessen the risk of that happening - just by punching that little "on" button each night.
