Shift work is difficult, when you take your levimer at 8am does it make a lot of difference to your control?
I say this because before I went onto the insulin pump, I injected my levimer at 11pm and 11.30am sometimes for some people, as slightly off set time of injecting works better than a strick 12 hour split?
If you are doing shift work, it might be an idea to ask your diaebtic team if you can be funded for an insulin pump, this would enable have different profiles (amount of background insulin deliver durning a 24 hour period) I have 4 different profiles on my insulin pump set up (max 5) nonwork day, active non-work day, 2 work profiles depending which kennel blocks I'm working in at work... I just swapped to the appropiate profile as required, if I have an half day at work, I switch back to non-work day when I finish... It makes controlling my diabetes a lot easier and a lot better as well
