Take it easy on drinks with caffeine: Coffee, tea, carbonated beverages!
I seemed to need to pee constantly when my sugar was high. I nearly wore out the carpet to the bathroom. The Dr found my elevated blood sugar when I was in the hospital for another reason. They gave me insulin, changed my diet and got my numbers down prior to leaving the hospital.
I cut all the sugars, desserts etc. They gave me a insulin monitor and I took my reading 2x a day! Eventually I eliminated pre-packaged food, got serious about reading labels, and limiting serving sizes. Monitoring carbs and dropping 67 lbs in 2 years!
I can seldom successfully meditate now that I have such bad chronic pain. When in reality that is exactly what I need!
