Can you guys tell me how bad will it change my blood sugar level if i was 2 hours longer in the fasting procedure?

Since I don't: Understand your question it's hard to answer. If you were fasting and had fasted two hours longer, it probably wouldn't have made a significant difference in your blood sugar -- provided you're talking about a fast of over 6 or more hours. Your body has mechanisms to keep your sugar normal unless you have diabetes or other significant problem.
