Last week I bought a meter and took it with me to my visit with the nurse (hoping she'd show me how to use it - I am not very technological) - she told me to take it back to boots for a refund as it and the strips are available on prescription - free (has your doctor signed your free prescriptions form?)
The nurse played down the importance of having a meter (why do they do this) but I gently insisted giving all the right reasons to have one (she didn't have a leg to stand on - v satisfying).
So, go get yourself one on prescription (don't forget a good supply of strips - I recommend a months supply) and as advised further down start testing with what foods you eat. For example, I discovered that canned tomato soup is terrible for me - it spiked my BG right up but interestingly, packet soup is not so bad (less sugar I guess).
A low carb diet seems to work well for many - I am still trying to get my head around it!
Before I was diagnosed (only recently), all I seem to have ate historically was carbs (they are everywhere - I just didn't realise). I used to also drink at least a pint of OJ or Apple Juice each night (can anyone else relate to this?) - I digress. Anyway, life should not be too draconian in terms of diet and if truth be told, I am actually enjoying trying new health foods and since been diagnosed and now starting to effectively manage my type 2 D, I feel much better

- when first diagnosed, my BG reading was 18.7!!!!! now right down to 6.7. Best of luck (I hope my story has helped) - let me know how you get on (add me to your friends list if you want)
