text: has anyone ever had a sleep study?   yes, i was found to have sleep apnea and am now using a c-pap machine..they put electrodes all over your head and things on your eyes and fingers etc..and watch you via camera while yu sleep recording everything...it's not that bad but is a little..i found i was getting almost no stage 3 or 4 or rem sleep --all restorative..just light surfacy sleep.  .i still think i have problems though and no energy and other related symptoms of sleep apnea almost 30 years.  go for it especially if you snore..have someone observe you to see if you snore r kick in your sleep.
