I'm an adult, and came across this site after my experience with Chrystal Light today. Over the last few months my blood sugar readings have been so much lower that we reduced my mealtime insulin from 8 units to 4, and sometimes less. Things have been going very well. Today I ate one meal at 2:30pm. Deli turkey on 100% whole wheat bread. My readings in the am was 109. During the day I drank water and a fairly large amount of CL. At about 4pm I felt awful and was sure my sugar was low. When I checked it was 225. I am 100% sure it's the CL. It's making more sense as I read and continue to check my levels. I've drank CL for years and never thought to connect the two. I hope this helps someone.
