It seems like parasites are stealing your sugar, and you need to add some complex carbs to balance your system. Same as you, when the parasites issue started I was running low blood Sugar every evening after supper for weeks? That's when I first realized that I had parasites.
Then it took a lot more Sugar just to reach between 70-100. I finally got to see my Dr. and he took me down to 1 shot of Lantus a day, instead of 3 shots of Novalog, and 1 shot of Lantus daily, and that presently works for me.
