I am refusing it, and I had GD last time around. I have refused the standard test, where I drink more sugar than I consumer in a week and feel ill for 3 hours after being starved the night before. I am, instead, doing two fasting glucose draws a few days apart- and a total blood sugar count after a meal. It's a pain to get into a lab first thing for the fasting draw, but I am just not going to drink that drink. If they offered my organic juice I might reconsider.
