I was the one who suggested a sleep study to my doctor. I had been on and off Zoloft, exercised, ate the right things. I was still waking up at night. Everything from gasping to screaming, "I'm dead! I'm dead!" I thought it was PTSD from my son's passing. Guess what? Sleep apnea. I have had my CPAP machine for two months. First thing I did was wean off my meds for depression. I'm 54 this month. I wish I had had sleep studies 10 or more years ago. At first, the difference in energy level was miraculous. I'm dealing with minor mask adjustments now. Mostly the nose bridge and air blowing in my eyes. I'll get it eventually.
