I love getting a massage - sadly, I haven't had time or money for one since we've been in Atlanta.
Most often, though, I clean my kitchen (something about having that whole room clean makes me so happy) and take a long bath with my nook in a ziplock bag so it stays dry. The baths are more necessary than pampering (I have so many skin conditions, and a long bath in colloidal oatmeal makes it all better) but the long chance to read with no distractions is the real pampering. The dog doesn't bother me while I'm in there, either!
