I'm hypothyroid (Hashi's) and used to have severe hypoglycemic symptoms when I ate CW. I had to eat often, and when I crashed I had to eat NOW. I would get the shakes and brain fog so severe I couldn't function unless I ate immediately. When I switched to primal, that went away. I think avoiding all the carbs in CW was the key, but not sure. Just know that I can eat the standard 3 meals a day now and I'm fine. I even go 2 meals on many days and am fine.
