1) Drink your caffeine like you would be taking a medication (i.e. regular doses at regular intervals) 2) Don't consume too much caffeine. I drink 4 shots of espresso in the morning and 4 shots later in the evening. I used to drink 12 shots total (4 shots, 3x/day), but began to notice that I was suffering from adrenal fatigue where I could function even less if I didn't get the first dose in and each dose didn't last as long at keeping me wakeful, so I cut back to 2x/day. Along with that, have a proper diet which may include certain supplements (Vitamin D, B12, fish oil), and make sure to get exercise in at least 3 times per week focused, and get up and walk around every so often, doing air squats or something, or simply take a walk around the block.
