Just wanted to throw this out to you guys. If you or you SO snore you probably have it. I very much recommend that if your insurance will allow it get yourself tested for sleep apnea.It slowly creeps up on you and you will think well I am just getting older. It can cloud your thinking, make you feel tired even if you think you slept well.If you or your SO fall asleep easily just sitting in a chair,could be sleep apnea, it is a silent killer. Also sleep apnea was causing a lot of cardiac problems with my mom until I insisted on a sleep study and she sure had it. The cpap mask she wears makes a big difference in her mental/physical status and also her chronic pain status. So if you haven't had a sleep study please check into this. Also if you dislike the thought of wearing a mask at night they have come out now with so many user friendly variations of sleep mask, I now have one that is designed just for women who like to sleep on their sides.If you can just sleep one night with one on after being diagnosed, believe me when you wake up the next AM you will feel like a new human being and that is when you will realize how bad you have been feeling. Like I said it creeps up on you and you start to think well this is just how I feel. Just my 2 cents.
