Hi, I am type 2 diabetic patient. I have observed the same. I have been on maximum allowed dose of medication for a number of years. This has not been effective enough to control my blood sugar level to acceptable levels. I have been advised recently, that If by next review I still have not been able, with appropriate food diet, to lower my sugar level, I would have to start to use insulin injection. Something I try hard to avoid. I am very concerned and worried about this. I hate injections. :-(
