Geez, there's a lot of you out there, that's a comfort. I agree about the sleep patterns, I'm totally screwed at weekends - asuming I get the weekend off - or the first three days of normal hours. I don't have a set pattern, I have to work as and when, so I can't regulate anything around it.

And regretably, I can't have any tunes on headphones. My work is of a "delicate" nature, and my headphones are tuned into something quite different. I only get to do this in my break, because the computer is supposed to be tracking something else.

But it's great to know that I'm not the only one out here.
