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.
I also try and do things really methodically – so leave my lantus alone while adjusting humalog – never both at the same time as I won’t know which is actually making the difference. I only adjust one ;
