85 degrees? Yeesh...wish I had that problem! Come to Chicago between October - April, you will be begging for that heat!
As far as sleep goes, only time will truly get you back to baseline. If you are anything like me, you have disrupted your body's normal sleep cycle for years on end, and it takes not AS much time to get back to normal, but still more time than 10 days.
If it persists, do as Dee suggests, bring it up to the doc you are planning to see. They will be able to offer better medical advice than I can. I am not a doctor, though I played one to myself for many years unsuccessfully.
