I really cheat. I have a fairly large office with all the comforts of home (tv, dvd, stereo, 46 gallon aquarium etc, etc) I also have a two drawer lateral file cabinet that is stashed full of clothes. Top drawer clean, bottom drawer dirty. I swap the clothes out every week but I could survive two weeks easy. Only thing I don't have is a shower and I am going to come up with that sooner or later.
