Along with my vitamins I take a cinnamon extract tablet. It works.
We drink our coffee strong, I mix Community Coffee with 1/2 Creole coffee in a 2# Flogers coffee container. lol
Mister Gee takes a cinnamon tablet also. He is a diabetic and tries anything and everything he reads. I also like my coffee strong, but he like his medium. I worked for the Navy for many years where the coffee was like mud and it was a crime to wash the pot.
