I might be going under, and i am prepared for a lot of pain. For those of you that had sleep apnea, how long did you have to stay in the hospital? I have chronic tonsilitis and sinusitis on top of sleep apnea. I am a 29 yo female, with fibromyalgia. ugh! Feel free to pray for me! any tips would be helpful! I plan on getting a humidifier. I know I will need it. Plus codeine makes me nauseous.
