Yarpy is right in that after 5 days of earlies you are getting tired. I find that by sleeping properly ie going to bed early so you can get up early, stops me getting realy tired, as the saying goes you cant burn the candle at both ends. I also find that by day 3 I am getting used to getting up early and that in return makes me less tired.
It is great being able to have some form of normality in a job that is inherently unstable. I used to be in the RAF and the hours we flew there were plane rediculous at times.
Nice to see someone being constructive with a sensible reply Yarpy, as opposed to just opening their mouth....
