I had the same post-surgery problem, too about a year before I found out I had sleep apnea. It is absolutely vital to tell your anesthesiologist ahead of time that you have sleep apnea so they can monitor your stats and the amount of anesthesia they use more closely. Also, we're supposed to either take our CPAP with us or make arrangements to have one at the hospital to use during our stay.
