Hi friend, if your just beginning
cpap treatment hand in there. Depending on apnea events prior to sleep study. Process will take awhile for your brain to retrain and adjust. My sleep doctor told me, that when patients begin cpap treatment, brains have to be retrained, because prior to cpap, our brains were trained to be alert, in case of stop breathing event, never going into a deep sleep state. The longer a person uses cpap, the brain learns to calm down, allowing deep sleep.
