I like the taste of bulletproof coffee. You can add some other stuff to make it even better. Try adding a little vanilla extract and/or cocoa powder.
I have just about stopped making bulletproof coffee though because my weight was creeping up and I honestly did not seem to get any boost, mentally or physically. I was making ~20 ounces and drinking that instead of my typical black coffee that I bring from home. In the end I do and feel better when I am Intermittent fasting without any (fat) calories in the morning.
Some of you may die, but that is a risk I'm willing to take.
