Although there are many things, you can do yourself regarding sleep apnea, don't forget the help of the medical community. When dealing with a problem as serious as sleep apnea, you need to seek the help of a doctor as well as a sleep clinic in order to avoid any serious medical problems.
If you have sleep apnea and have been using your current CPAP machine for five years or more, see if it is time to get it replaced. CPAP technology is rapidly changing all the time. Many insurance policies allow for a new CPAP machine every five years. If yours does, consider upgrading to the newest CPAP so you can get the best treatment possible.
