I know what you're going through, as I went through the same thing when I got mine. However, it does get better. It took me about a week to get used to it, and now I wouldn't sleep without it. Most people struggle with it at first, its normal. Just concentrate on taking in nice deep, slow breaths, and before you know it you will be asleep, and wake up feeling refreshed in the morning. On a side note, tell your doctor you want a prescription for Provigil(Modafinil), as you have a diagnosis of sleep apnea so your insurance will cover it. You'll never be tired again between using the CPAP and Provigil.
