If ND were to design an energy drink

I know it's difficult to reinvent the wheel on energy drinks. 99% are some variation of high dose of caffeine + B vitamins.

Still, as someone who rarely goes a day without an energy drink, I'd be curious to hear what people in this subreddit would look for in a uniquely ND take on the genre.

I also wonder what's possible and impossible to include, both in terms of formulating a carbonated drink that doesn't have any 'silt' in it, and in terms of regulation and marketing rules.
