Nan, I echo the others. Eat all your allowable carbs. And eat often. This way of eating actually helps control my hypoglycemia. But I often find a need to snack. My meals are not often eaten just in one sitting, but over a period of 1-2 hours. I often must have something before bed, or I will wake up with a blood sugar of 3.1. 3.7 is pretty low, but probably not dangerous. Still, the symptoms are not fun, and it is your body telling you to raise your sugar. When you start to feel your sugar get low, snack on nuts, cheeses, vegetables. Why not give it a 2 week try at 20g, and see what happens, both with the low blood sugar and with the weight loss. One suggestion for the fear you have on eating the carbs. Why not use the ketostix to check through your day as you're eating them. You may find yourself able to eat 20, 30, maybe even higher; seeing that you're still in ketosis, which means you're burning fat, could ease you're mind, that you're not wronging yourself by eating the carbs.
