I'm in total agreement to the posts above, however I'm not a pilot (yet).
Please don't under estimate how tiring a lengthy commute can be on top of a full days work. I have a long commute, approximately a 4hr 20mins round trip per day from the Midlands to London and in my opinion on top of a full days work it is totally unsustainable. You may find that renting a room locally is more affordable than cost of fuel or trains!!
