Hi all, Yesterday I had a bit of a nightmare, bgs were between 10-18 until around 7pm after quite massive corrections (around 6 units every hour?) and then they finally got in range until this morning, where I have swung up to 15, with a larger than normal bolus for my breakfast and another few correction units to hopefully bring it down. I went through all the possible causes, and am not ill or falling ill (unless there is an infection hiding out), made sure I was using relatively unused injection sites and changed my cartridges on both my bolus and basal pen. My basal was fine overnight so I don't think that is the problem, but my bolus does not seem to be touching these highs. Any ideas or suggestions apart from giving monster amounts and hoping it doesn't crash?
