Top Secret Recipe Version, from Todd Wilbur. He says the secret ingredient is cinnamon (cassia) oil, and he says it can be found at health stores with the lemon and orange oils. He also specifies that it important to only use one drop of the cinnamon oil because it is very strong. The NoDoz should be crushed with a mortar and pestle or in a bowl using the back of a spoon. Do not substitute Vivarin for the NoDoz because it tastes bitter. I haven't made this so if you make it please post a review and let us know how it turned out. PLEASE NOTE, YOU WILL NEED 8 NODOZ TABLETS (200 MG EACH). THIS IS NOT IN THE INGREDIENT LIST. I was unable to add it to the ingredient list due to recipezaar not recognizing it.
