My sugar was 139 before I ate this morning. My meal had 50g of carbs. One hour after my sugar was 272 two hours after it was 222.
I personally believe your carb intake was too high as well. I was recently diagnosed with type 2. Sugar was at 402 and los 60% of my vision in one night. In 2 months I dropped 28 pounds and only ingest 15-20 carbs per day. I was originally prescribed metformin 800mg x 2 daily, glimperide 2mg x 1 daily and lisinopril 5mg x 1 daily...in 1 month, I cut my metformin in half to 425mg x 2 daily and stopped the other two entirely and now at 2 months I stopped my metformin. My sugars normally range 80-115. After meals I am at aroud 120-130 after 2 hours. I exercise daily and I use my food as my medicine!! I am now eating to live instead of living to eat! What a wonderful change.
Did you take your medicines? Your carb intake was way too high, in my opinion. Dr. Richard Bernstein recommends only 6 grams of carbs in the morning and 12 at other meals. I use 15-17 units of comination insulin and eat 20-30 grams of carbs for breakfast.
If you are not using insulin or other drugs, I would suggest that you eat fewer carbs--and also if you are using drugs.
may be you need to do exercise more often
