Lee do not dispair.I can suggest what I have done as a Type 2.
You have to keep off carbs that is most important.Eat more fruit and veg. (eg Blue Berries). Keep off alcohol,it has lot of calories. (if you need it be very moderate)
I eat lot of fruit, brown rice (brown basmathie),try and eat more fish.Try to eat your evening meal between 6-7 pm.Also remember to go for a walk after the evening meal.I walk twice a day in the morning as well as in the evening. Avoid fizzy sweet drinks.( THESE HAVE LOT OF CAORIES). I have managed to halve the INSULIN level, which I take in the morning as well as in the evening before my meals.I take INSULIN and METFORMIN.
Also if you can eat BITTER GOURD (Karilla sold in Indian groceries), has to be cooked with spices, it is very bitter.This reduces blood sugar, very effective. Also cinnamon powder mixed with your rice meals.Cinnamon has cromium, which is needed by Pancreas. My BG varies between 4 and 6.Remember exercise is very important.If you can discipline about eating less carb,eating at the right time and exercising, you should, be able to reduce your BG. I can asure you.(REMEMBER TO KEEP SWEETS IN YOUR POCKETS, AS YOU MAY EXPERIENCE HYPOS) GOOD LUCK.
