I don't know what your blood sugar level means in terms of good or bad. What I do know is that if you are trying to control your diabetes through diet and exercise, you should do it only under the supervision of a doctor. I hope this is true already.
I don't have diabetes, but I am hypoglycemic. Diabetes and chronic hypoglycemia run in my family. Both are related to insulin production (diabetes is too little, hypoglycemia is too much.) I have learned to control my blood sugar through diet mostly. I usually only have attacks during periods of high stress when I don't eat right, or when I consume too much caffeine.
Up, up and away!
