Welcome to the forum, Steve. It sounds as though you are doing all the right things and congratulations on your weight loss. I was diagnosed with Type 2 diabetes 6 years ago and am still on diet only. On diagnosis I was given some wrong advice by my GP about what to eat, being told to have brown rice and pasta. However, I got a meter and found out that even brown versions of those two staples sent my blood sugar levels soaring. I haven't eaten them since. I have cauliflower rice with my curries, stir fries or chilli con carne now. Two weeks ago I came across the website below which has some very interesting low carb recipes. I have made the cauliflower rice with mushrooms and spinach and it is delicious.

I don't know of any support groups but I joined a diabetic forum shortly after being diagnosed and found it very helpful. When you are taking your blood sugar readings you need to test just before you eat and one and two hours afterwards to know what foodstuffs to avoid in future. Details here:

This past year though I started to eat some cakes, chocolate and ice cream and my HbA1c has gone up to 59, surprise, surprise! I took myself in hand a few weeks ago and went on the Newcastle diet. A friend on a forum had told me that the Daily Mail had published details of it. I found it online here:

I have also found that my meter readings when I wake up have dropped from 10 or 11 to between 6 and 7. I am still on Stage 1 but am over one third of the way through it.
Good luck Steve; keep up the good work!
