Thanks both. I am low carbing but my blood sugars are still rising, it feels as though the Victoza has switched off so I am wondering whether I am no longer producing as much insulin as before so it's not as effective. I am worried about weight gain as even though I've lost 2.5 stone I still have a lot to lose. I am sedentary because of back issues and both parents are diabetic. My Dad had a very strong CVD history so I don't want to risk future complications. Metformin hasn't had any impact and I was successful with diet only for about 4 years but then no matter what I did the sugars went up which is when I tried Victoza. In truth I've been trying to ignore it for a couple of months in the hope it would all go away or stabilise but it doesn't appear to have done. Tablets don't seem to be an option any more from the GP perspective.
