Hi Trealan
What is your diet like ? Have you tried a low carb approach to your diet ever ? This approach does work for a lot of people. What is your BMI, if you can get this in the normal range this will certainly help with insulin sensitivity, also cardio exercise daily for an hour to get your heart rate up and work up a sweat will really help with insulin sensitivity also...the more the better.
If you have already tried all these and your pancreas is just burnt out now and you are hardly producing any insulin, then you have no choice, you will need insulin to stay healthy.
Insulin is no walk in the park and if I had ANY other option I would try my upmost to do these instead of having to inject and the side effect of this treatment is Hypoglacemia ,which is a pain ,manageable but a pain.....So if you have other options left open to you ,my advice would be to go for these with all you can muster to stay away from insulin. Only you know the answer to this, an Endo will just go on your Hba1c and try whichever course of treatment is next to get your numbers right...
Just look at all the hassle with the DVLA which is hanging over insulin users heads, If you REALLY need it ,then that's that really ,but if you are Type 2 and can put it off for as long as you can with lifestyle I would go for that.
Hope it works out,whatever happens.
