Not even. I can't speak for others but the effects of 5hr Energy pretty much disappear after those 5 hours are up. Half the caffeine dose isn't enough to do much of anything, at least for me. So it's essentially a waste. I'm sure it depends on things like BMI but to get 5hrs of half-assed energy you'd need to consume 3/4ths of a dose, which would leave you with roughly half the experience of a 5hr Energy (that is, half the difference between the caffeine in your system immediately after drinking one dose and 5hrs after drinking one)

Except you've already had 5 hours of your body metabolizing caffeine, so the effects of the remaining half a dose after 5 hours aren't nearly the same as if you took that half a dose after a night's sleep and not having had any. Your body becomes accustomed to it. That's how all drugs work. You can take 6 grams of mushrooms and it'll definitely still be in your system after 6 hours, but the effects won't be the same as taking 3 grams straight up, it will have almost entirely worn off despite the residual psilocybin in your body.
