First of all let me say that there is no shame in going on meds if you need to, ok? Let your doctor be the one to decide how and when. The only thing that can be a problem is if you spend a lot of time trying to get numbers in line with 'natural' cures like cinnamon or bitter melon when you could do it overnight with oral meds. Whenever you are at 150 or above two hours after a meal you are doing permanent damage to your eyes, kidneys and blood vessels. So however you need to get the numbers down, do whatever it takes.
To answer your other questions, yes, you can level out and bring your numbers down with weight loss and exercise as well as diet but diabetes is sneaky. One of our members, Warren, was a regular guy without a speck of fat on him... exercised regularly and took good care of himself. He had no history of diabetes or any major health problems. He was blindsided by Type2 diabetes and very quickly progressed from oral meds to insulin. So before you get concerned about the taking of meds or not, you need to know you are a T2 diabetic for life. We can all be controlled diabetics with exercise, food plans, and oral meds or insulin. Or we can be an uncontrolled diabetics and eat whatever we want, drink alcohol, not exercise, smoke and generally ignore all common sense. The overall length of our lives will be about the same, give or take ten years or so... But the quality of life is where the difference is.
My father-in-law ignored his diagnosis for years and ignored his food plan. He was finally was put on insulin. He shortly thereafter went blind, got neuropathy in his feet and had two heart surgeries. He was miserable and suffered a heart attack and died. If nothing else he did me the service of showing me what not to do.
As far as testing goes the best times to test are very first thing in the morning before any food or coffee, before lunch or before dinner and before bed. Probably the wisest thing you can do for yourself at this time is to start a little notebook with a journal of foods eaten, amounts, sugar readings two hours afterward and how much exercise you got. By doing this early on I learned that white rice, corn meal, pasta and potatoes are pretty much the same for me as eating candy. My body reacts to them by spiking my sugars very quickly. Brown rice, bulgar wheat with oil (tabouli) instead of pasta and small servings of potatoes are my way of dealing with this. I can eat corn on the cob but cornbread and corn flakes are out for me.
Everybody's metabolism is different and we each have different speeds of digestion as well. The secret to keeping sugars level and healthy is to eat lots of veggies, less starches, and very little refined grain products. Processed cereals, white rice and pasta have already broken down or removed the cell walls and hulls of the grain so the starch is exposed and readily absorbed in our intestines very quickly. Simple grains like old fashioned oatmeal, barley, brown rice and bulgar wheat berries are in a basic state, very un-processed. It takes a long time for our bodies to mechanically break down these forms of grain so the release of the carbs they contain takes much longer leading to a time release of sugar/carb into the blood stream. This helps prevent spikes. The addition of fats as well as protein with these foods slows down absorption as well and is better for us.
I've probably overwhelmed you with all this so I'll stop now. Just know that you are on the right track and you can do this. You have a good attitude and an excellent doctor who pays attention to your labs. Hang in there girlfriend and we will be here for you.
