Hi . Is your sleep apnea due to obesity? Do you use a CPAP? CPAPs can be challenging, but I also moderate in our sister community for people with sleep apnea (SleepApnea.Sleep-Disorders.net)and my husband has used a CPAP for more than a decade. So, I'm happy to help if you are ihaving any issues using it. They can take time and a lot of trial and error to get used to. Warmly, Lori (Team Member)
