Buy a carbohydrate counter book, Amazon is good for them. The start cutting out asmany carbs as you can. You probably need to get down to 80 - 90 grams of carbs a day, but everyone is different, you might handle more or less.
Alcohol is bad, at least for me, I do enjoy a glass of something, but I find that I simply do not stop at one, so for me, it's no alcohol at all. Red wine can reduce your blood sugars and so can all alcohol, it keeps the liver so busy getting rid of the alcohol from your blood it has no time to pump glucose into your blood stream.
It will also push your blood pressure up and that can lead to other complications.
Buy a blood sugar test meter or ask your Doc. for one, and the test strips to go with it.
Test to find out what carbs you can manage and how much. Test in the morning before eating, maybe before and after lunch and before and after dinner. Keep a record of your readings and your food intake. You will soon see what you can and can't do.
Then when you know what you can handle you can ease right back on the testing, just test if trying new foods etc or if you are ill.
Smoking is not good for T2s, we already have an increased risk of heart trouble so anything that makes that risk even worse is a no no.
I know it's not easy stopping, but you have made a start and if I can do it so can you
From your figures you are doing OK, you need to get them down as much as you can, and you will find some advice on here elsewhere.
When you see your diabetic nurse ask questions, and take a record of your BG readings and food eaten, times dates etc., it will impress them! It also shows you want to be pro-active in managing your T2, and have made a start at this. You need to be in charge of your day to day management, and keep an eye on your treatments and results. The Doc and Nurse will (or should) take overall charge of your T2. but don't take your eye of the ball.
Good Luck and keep us informed.
