I find that energy drinks help me sleep better. If I have some strong in the morning despite not at all needing one, I'll be more tired and ready to sleep that evening.

It probably has not-healthy side effects so I'd not recommend this day-to-day for anyone, try to avoid this myself as well.

Coffee and energy drinks saturate the receptors in your brain that trigger tiredness, such that you don't feel tired.

You brain, in response, build more of those. That's why coffee is less efficient over time, and why you feel more tired without coffee when you are used to drink some'

I'm sure this is what's happening long-term, but would this have any effect within a single day?
