I am type 2 on metformin and insulin.
After being diagnosed nearly 5 years ago I did the diet and exercise, then the tablets but for me it didnt really work. My levels came down for the first couple of yeaes then crept back up to the point where my diabetic nurse reckoned I could eat dust andit wouldn't make a difference. Started the insulin, just once a day, just before Christmas and its made a huge difference. I've found it a doddle and really easy to manage.
