Two things for me.
1. You need to tell the DVLA about your diabetes, and ALSO your insurance company. I got told about 5 different times about the DVLA part but never the insurance bit.
2. What rotating sites actually means - you get told it's important, but every time I've asked for how to do it I just get told it's to stop lipohypertrophy. Does that mean I can use the same site several times in a day and then move somewhere else tomorrow? Move site everytime? How soon can I go back to an existing site - a week later? A month later? So far I haven't managed to get a clear answer on this from any nurse or doctor.
