I was diagnosed with moderate sleep apnea about 8 years ago. I went strict low carb, lost weight, and in a 6-month follow up, I no longer had it. Good suggestions here, and achieving and maintaining a healthy weight along with getting a good night's sleep were keys for me in correcting the apnea. I still have to watch it closely, but knowing it can be managed has made all the difference. I would go to a sleep specialist who can prescribe a device for an at-home sleep study to confirm. Much better than going to a sleep lab for one night. I could never get to sleep in those environments.
