I've actually thought about this subject a lot... it's suicide of course, unless you get picked up hitchhiking somewhere in the galaxy...
I think it would be great to have a vaporizer, enough food, water and cannabis for a year, my MP3 player and the views of space all around me in a little cocoon.
Just remember to hang around in LEO and build up that escape velocity (10.9km/s) or else you'll go nowhere.
