The obvious would be helpful too!
Number one: Never clean with peroxide, alcohol or neosporin. -Get yourself a nice antibacterial soap without lotions, dyes or scents. (Try Satin) As for sleeping, my suggestion is to bend your arm under your head in a triangle fashion and to keep your ear in the little hole so it won't be bothered much. Sea salt soaks! They can really change the healing process right around. They're easy to do and well worth the time. Good luck!
