Whilst everyone is not the same, CPAP users often report improvements such as less irritability and better concentration. You may also find that you respond better to the treatments given for other health related issues and you will be less at risk for stroke, heart attack and respatory problems. It is very important that you tell your regular Doctors that you have started using CPAP. You may require changes in your medication if your conditions improve. ALWAYS consult your Doctor before changing anything.
