Hi, I'm Carol, been on CPAP since March 2015. I was diagnosed with moderate to severe OSA. Still waiting to feel less sleepy and have more energy, but at least the therapy has eliminated my snoring. I have a love/hate relationship with CPAP. I alternate between looking forward to going to bed and dreading it. I've gained about 18 lbs. since beginning CPAP and that has me really disappointed, especially as my doctor had promised weight loss and energy as side effects of therapy. But I know I have to stick with using it. Am glad to have found this Forum and look forward to learning and sharing with all of you.
