After you get accustomed to a mask and hose, you don't even know you're wearing one.  

THEN, do yourself a HUGE favor and buy a travel cpap.  I have the Resmed air mini.  It works fantastic.  Very small and easy to pack. Plus you don't need to pack up the regular machine and way more convenient when you come home to not have unpack the regular machine and set it up; it's already set up. Highly recommend a travel machine.
