Five Hour Energy: Mother's Little Helper comes in a tiny bottle these days....

You COULD stay hydrated and consume a balanced diet with an emphasis on fruits and veggies and lean proteins.

You COULD re-evaluate your schedule and be realistic about what you can get done in the time you have, taking into account that your body needs adequate rest and that the world's wants and "needs" kind of need to respect that- and will, if you make it....

Or, you could ignore your body and chug a little bottle of caffeine with sweeteners.  You'll get a momentary little energy high that will allow you to be productive for a few more hours, and your body will just have to deal with the fact that you used this artificial junk to cover up it's natural warning signs because you're a Superperson after all and You Don't Have Time to be Tired because look at this work you have to do plus your kids want- sorry, "need" you to be at 100 percent all the time.

So pretend that your body is just like your cellphone- with the right addition it can be recharged super-fast with no ill effects.  Just take a swig of this stuff and get back to work, monkey.  Natural vitamins?  Rest?  You sound like your parents- you know, those people who are still active and healthy into their eighties because they understood that it was ok to take a break now and then.  What dopes, huh?
