My diagnosis is Moderate Obstructive Sleep Apnea.  I have Excessive Daytime Sleepiness.  I had another sleep study with CPAP last night.  My tech said she had me titrated up to 14.  I get my CPAP tomorrow.

With my OSA being on the low end of moderate, do my numbers really warrant having CPAP?  I've heard that some doctors won't treat people at this level.  My doctor seems convinced that I need the CPAP.

Is it reasonable that I will feel significantly better with CPAP?  Or are my numbers so borderline that it probably won't make much difference?
