I made a move like that once, just before grad school. My roommates hadn't announced their plans...
Three days before electricity. Day one, decided shaving by candlelight was a bad thing. Day two, started growing a beard. Day three, learned about the need for conditioner on new beards. Met the dear goodwife a year later; she's never seen me without it and hopefully never will.
It's not a problem for me. I use an electric razor.
