Rory they didnt find any answers, smiling. It must be frustrating, but presumably they ruled out some horrible stuff too (which is, at least, something).
It's crap that your bosses are being difficult about organising your shifts, fuzz. I think I would struggle to choose between doing the hours over fewer days or doing shorter days too. It's really hard to judge. Early starts and late nights are not helpful ever. I hope the two weeks off and then reduced hours helps you.
I'm allegedly FT. I do work every day, but I never manage a full day. I seem to spend a ridiculous amount of time getting up, walking around and stretching. And I almost always fall asleep at some point in the afternoon when I work at home. I can't do that when I go in to work (and there's the bloody train journey and the fact that it's harder to go a-wandering every 20 minutes at work) so I'm more useless on the days after I've been in. So, I attempt to work FT and usually fail.
I have to go back in tomorrow. I would really rather not, but I have to. My hips are not going to be happy by tomorrow night. 
They're grumbling right now, which makes it hard to sleep. I'm waiting for some painkillers to kick in and (hopefully) help. On the plus side, I picked up my pay slip for March and I seem to have gotten an increment on my salary scale. I am considering using the extra money to buy first class train tickets instead of standard. It can't make the commuting worse.
Ah. My problems sound so petty in comparison to everyone else's. Sorry guys.
