Raised eyebrow at the lady who experienced extreme withdrawal symptoms after 48 hours of no caffeine and still wants to drink coffee... How on earth isn't that biofeedback to avoid an addictive poison?
Give it a month (or two weeks even) I promise by then you will be sleeping better and be more naturally energetic without the requirement of an outside drug. The way people describe the comfort morning coffee gives them each morning is akin to a functional alcoholic or smoker describing their drug of choice. Do what you want I just think you'd be in better shape as a physical entity without the dependency and negative side effects of caffeine and I'm pretty sure you'd feel better as well. I double dog dare you to give it a shot! What do you have to lose? Probably some light headaches and discomfort. Is that worth potentially better sleep and lower cortisol for a couple of weeks? It could be! Try it out!
