Try taking L-Theanine with the caffeine if you're going to take that much because it will help with dependence and adrenal fatigue. And frankly, I would take a much smaller dose, and generally never take more than 300-400 mg per day. I think you need something that works in a different way than coffee, as the parent to my comment says, look into nootropics. Reddit.com/r/nootropics/faq is a good place to start.

L-Theanine also seems to improve the effect of caffeine in me; the caffeine makes me alert, but the theanine with it feels like my focus can't be broken unless I want it to.
