Y'all need to watch Gordon's sugar levels closely during treatments, not so much for higher levels, but just the opposite. I was still on my Metformin for about the first 4 weeks of radiation treatments and started having trouble with my blood sugar bottoming out and even passing out a couple of times.
Side Note: About 6 weeks post, I was craving and eating chocolate chip cookies like crazy, with no adverse effects on my sugar levels.
