i'm tired all the time. how do i find out if i have sleep apnea?
Go to your primary care physician and mention that you are concerned you have some of common symptoms of sleep apnea (loud snoring, overweight, thick neck, depression, morning headache, irritability during the day, never feeling rested, and lack of concentration).  Then the MD will do some blood tests (thyroid will be one of them for sure) and will refer you to a sleep study clinic.  If you want insurance to cover it, you have to go this route.  Bad news, most sleep clinics take at least 1-2 months to get in... and the test you will be having is a polysomnogram.  They will hook you up to alot of wires and monitors and then want you to fall asleep.  Easier said than done, I know!
You need to go to the Department of Human Services (formally Family Independence Agency) and fill out an application.  They want to know how much $$ you have made this month and are planning to make.
