hi I read through your question and understood your concerns. -If I were your treating physician I would consider to 1st check if there is any co - morbidity that may cause a rise in the blood glucose levels such as: -thyroid profile (research shows that thyroid abnormalities are more common among diabetic patients) this may cause a persistant high glucose. -any other infection, etc -adding oral drugs like - metformin,linagliptine these will help decrease the insulin resistance. and increase effectiveness of insulin. -reducing the night dose of insulin compared to the morning dose may be beneficial: ie. because the insulin may cause a very much decrease in glucose that results in the body producing more hormones that increase blood glucose in order to prevent the body from going to hypoglycaemia.(somoyogi phenomenon) -most important of all: -have a strict diet control -go for a walk - eat food rich in fibre -avoid sweets,alcohol(if you have the habit), tea ,coffee etc -MAKE SURE THAT YOU CHECK THE EXPIRY DATE OF THE INSULIN YOU ARE PURCHASING. -MAKE SURE YOU MAINTAIN THEM AT THE REQUIRED LOW TEMP. IN THE FRIDGE. -AND TAKE INSULIN PROMTLY ON TIME AS ADVISED BY YOUR DOCTOR. WISH U A SPEEDY RECOVERY..!!
