I have a small tin of it at work, which I ordinarily mix with bai5 drinks, the ones with some tannin (e.g. pomegranate, blueberry) so the bitterness of the caffeine is less objectionable.
For completeness: I often have a single Mountain Dew on the way to work, timed to have the caffeine start hitting about the time I'm set up and working.
That's fine, and has worked well. It's classic agonistic usage of caffeine - reinforcing my most awake times with some extra stimulation and energy. It's a great way to provide a small but significant productivity multiplier on my work.
It also needs to change. I'll explain.
"Agonistic" caffeine usage is as opposed to "antagonistic" -- reinforcing high-energy times to hit higher peaks, rather than caffeinating when tired to get less extreme troughs.
Unfortunately, you can't do both.
You can burn more energy when you're up, you can burn more energy when you're down, but if you do both, you crash hard.
It's almost as though humans had limits. Damn us all.
Agonistic caffeine usage doesn't *require* a regular schedule, but it rewards it. Extra energy at predictable times and working hard early in the day mean more of a drop in the evening. You had extra energy and you burned it first thing in the morning. Great for your early-morning work quality, terrible for evening alertness. If you try to push yourself in the evening, you often just can't. That ship has sailed, that battery is dead, your butt is snoring on the couch at 8:30.
Which means if you're going to go out at night, you really shouldn't do that. Again: burn your extra energy early or late, but not both.
Suddenly, Krissy and I are out doing fun things in the evenings.
You know what I need to not do? Caffeinate hard and early.
This life, it keeps changing. It's almost like I'm not actually dead yet.
