You could drop a bit of No-Doz in your juice, might make it taste bitter though. Personally I hate pure caffeine. I find cocoa powder way smoother / less jitte

You could drop a bit of No-Doz in your juice, might make it taste bitter though. Personally I hate pure caffeine. I find cocoa powder way smoother / less jittery, and generally less fatiguing. Edit: sorry, I see, now, you wrote whole. Just swallow the No-Doz. But, again, while cocoa beans or powder for me.
