Hello Bob and welcome,
Andrew is quite right. Your diet is your problem, not your medication. Medication helps a little, but diet is the key. Meds won't do it on their own I'm afraid. If they did, none of us would be here on this forum.
All carbs turn to glucose once inside the system. Glucose is what we do not want in our blood stream. QED cut right down on the carbs, this will cut the glucose in your bloodstream and your levels will drop.
Rice, pasta, potatoes, bread, cereals and anything made with flour are the worst culprits and should be cut right down or avoided completely. It doesn't really matter what colour the bread is. Your meter is already telling you this. Eat plenty of leafy green vegetables, meat, fish, oily fish, eggs, cheese, dairy products (real ones, not low fat). Have bacon and eggs with tomatoes and mushrooms for breakfast, or scrambled eggs, or eggs cooked any which way, or a full fat Greek Yogurt with a few berries thrown in. Be careful with milk and fruit as both are full of sugar.
Try this, and then test before you eat and 2 hours after your first bite. Record what you have eaten, including portion sizes, and record your levels alongside. Patterns will emerge and you will see for yourself what your food is doing to you if you compare 2 meals - one normal one and one low or no carb one.
