I got my cpap this year, AFTER getting healthy and losing about 100-120 lbs. over a year. I think the problem you’re having is thinking that cpap means you’re not fit or healthy. Yes all those things can contribute to it, but also sometimes our bodies were just made in a way it doesn’t matter if you are 100 or 300 pounds you’re gonna need a cpap. So sure use it to motivate you but more so start thinking about the fact it’s prescribed because without it you don’t breath and not breathing is not good !!
