My caffeine intake fluctuates in an almost cyclical pattern. I'll injest a lot to the point of ineffectivness, then scale back to nothing, then slowly ramp up again. It's not purposefull, just a natural progression I tend to follow.

Right now, I'm off it completely. I'll stay this way until I have a day where I'm really tired. I'll break down and have a cup of coffee. That's usually the breaking point for me.

At the max, a day could be two Monster energy drinks, four to five 12oz cups of coffee, and an occasional cup of black tea. A few days at this point and I feel nothing from it, and begin to scale back.

I haven't gotten to that level since starting on ADHD meds. Turns out I was self medicating without realizing it.
