You probably have tried a sleep study to see if you gasp for air. I have sleep apnea and use a CPAP machine. If I don’t use it, I wake up with a terrible headache, tired, and many of your symptoms! Also, I found out that I had many symptoms from taking Prolia. I hope you don’t take any bone strengthening drugs because hey can sometimes make you very ill and doctors don’t know why because their tests all check out.
