How to get my diabetes under control fast?

Fast may not be good: Since your body has adapted to living with high-sugar state, rapid drop to normal range may cause relative hypoglycemia (dizziness, blurry vision, weakness, sweating, even passing out). Diet/exercise, and wt loss if obese, is always advised. I would consult doc and and nutritionist/diabetic educator and work out a plan than is safe and maintainable over time, a life-time. Consult doc. Good luck.
