Great thread.
I find the move from 9-5/6/7/8 to a roster quite a worry too. It's not because I don't enjoy my flying, it's that I love going out with the beers with the boys quite often too!
I think it's a fairly natural worry to be honest - unless you have no friends and sit at the end of your nearest runway with a thermos and your best mate Dave - the scanner!
Cheers
