Hi Sarah,
I get odd readings all the time - with greater understanding you can actually work out why..
Firstly testing after 2 hours will give you a high reading - why do you do this ? Your quick acting takes up to 4 hours to leave your system, at 2 hours after eating your BG will at it's peak so taking more insulin at this point is dangerous as you will go low - then have to over compensate by taking more insulin so you will be going high and low and playing catch up all the time - avoid the temptation to test until you next eat, then take your correction with your insulin requirement for that meal.
There are lots of variables as to why we run high and low - insulin resistance due to hormones, stress, incorrect calculation of carb ratios, heat, exercise etc, lumps at injections sites, insulin that's gone off, time it takes for insulin to work with the carbs. Taking insulin before meal times is advisable as it's already in your system and working by the time your food hits your stomach.
Personally I dont test unless i'm driving or until before my meal and I take action only then or before bedtime.
I always seem to be advocating it and believe every type 1 should read it to know more and manage their diabetes better but Dr Bernsteins book has been a great wealth of knowledge for anyone who doesn't want to live with complications and have a better life should read it.
