Hi coralkay
I'd take a deep breath and start to do everything your Consultant has asked whatever you think about it. Yes, it's an effort sometimes but start to test and record your blood sugar whatever the result, write down what you eat , how many carbs you have, what bolus you have, basically get into a routine of recording everything you do diabetes wise. You will start to see patterns once you have recorded everything for a few weeks and there is always a pattern, high or low. That gives you so much information to show your Consultant and to show how keen you are to get good control.
Small tweaks here and there can make such a difference and it maybe that you start to get better control on MDI, perhaps you'll still have problems that require other methods of treatment but without testing and recording regularly neither you nor your diabetes team have much to go on.
Don't despair, it is hard and monotonous, so much affects blood sugar and none of us want it but that's what we got given. Start a new page and put a bit of time each day into recording what's going on, good or bad and hopefully that will start to lead to improvements for you.
