A few months ago the doctor told me, (I'm paraphrasing) "You're fat and you snore." I think his bedside manner was a lot better than that but the message was that for my own good, less was more. He recommended a couple of free apps for my phone; My Fitness Pal, and Google Fit. I can extend his recommendation to any of you who want to ditch a few pounds.
So the snoring (which is always abnormal, as the sleep doctor told me) is made worse by the excess weight. So if I actually lose enough, maybe I won't have to sleep with a CPAP machine.
