There are many symptoms to sleep apnea. I didn't know I had been having trouble breathing either. I didn't know i would stop breathing...although I did have many times when I would wake in a panic, and think I was having a bad dream...which they tell me is an episode when the person stops breathing. Or if you gasp for breath, that too. It also has to do with the different stages of sleep, with apnea, some people never get to certain stages. Believe me, I was the first to think the doctor was crazy, yet I also read both of my sleep study reports. I also have a low oxygen level.

Have you read in any insomnia forums?

You can get melatonin any where you can buy vitamins, even the grocery store. I take 6 mgs every night...I use Natrol brand, but I have to be very careful because of my intolerancea, you could maybe try any brand.
