My number before supper last night was 135. I had BBQ pork sandwich, tomatoes, raw veggies, muskmelon, and a Chrystal Lite drink. When I checked my numbers 1 1/2 hours later my glucose was 220!! I can't believe that a "bun" would cause it to raise that much. So being frustrated, I took a bath, drank a full glass of water and checked numbers again 45 minutes later. It was 147. Why do they range so much? Was it the Chrystal Lite and the fake sugar?It was supposed to be a treat but if it raises numbers like that I guess I can't drink it.
