Sleep Apnea like symptoms after nasal surgery?

I had a septoplasty, turbulence reduction and adenoid removal surgery earlier this month. Since then I've been waking up gasping for air every couple hours throughout the night! When I first had the surgery done I was waking up every 10 minutes which made me have a horrible bout of not sleeping for 6 whole days. Once I finally did sleep I woke up VERY delerious/confused. My nose has healed well and there no mucous or blood. These symptoms only began post surgery. What could be causing this?
