Sometimes it takes a few days to adjust to sleeping with a CPAP, but when I first got mine, after that adjustment I began feeling stronger and more energized. It has been many years and this year I was beginning to feel more tired and weak again. Dr just upped my pressure on the CPAP so after adjustment again, I should start to feel much better. Using the CPAP can help with weight loss also because your body doesn't have to hold the fat working to keep you awake and alive.
Through God, all things are possible
