Hi Borderter
sorry that you seen to have hit a wall with your treatment, I do wonder though if meds don't seem to be doing the trick, I wonder if rather than being a type 2 diabetic, you are actually LADA/1.5 this is very similar to Type1 diabetes, and is often called slow on set type1 !
There is a test that your doctor can do, GAD anti-body test which should help depicted what is happening, but a classic sign of LADA/1.5 is that at first it's thought you are Type2 do oral medication is given, this either doesnt work or over time stops working..
If you have to go onto insulin, it's not all bad like any medication it has it con's such as increased risk of hypos but over all it does make diabetes a lot easier to control once you've got the hang of things and can give you more flexibility in food that you choose to eat..
