I don’t think there is such a thing as the perfectly controlled diabetic! I think it’s bordering on impossible to keep your levels within 4-8mmol/l all the time (and have a life!) However, my control isn’t too bad and I do it by testing, logging, testing, logging, testing, logging, looking for patterns in the results and trying to work out why I’m going high in the mornings, low in the evenings, high during the night. I then tackle each problem at a time – so I work on the high mornings and ignore the rest. Once I’ve got that sorted I move onto the next issue.
Eventually, after a lot of work, I’ve got reasonable control and the methodical approach works for me – but I still manage to completely screw it up from time to time!
