Spoiler alert: I’m going to share everything I know about optimizing your sleep in this Saturday’s issue of 66.1. I’ll cover:
Best practices for timing caffeine so you don’t disrupt your sleep

Ever spent a day driving across the country on a road trip, drinking as little water as possible for, you know, time reasons?
Or maybe it was on a flight.
Or a day out in the sun.
In the past month, I’ve had friends in all 3 scenarios complain that they had a migraine. If this is you, ibuprofen isn’t your answer.
Electrolytes are your answer.
Your body loses electrolytes in this scenario.
Not enough electrolytes means a headache.
Low energy.
It used to happen to me ALL the time after a long run, bike ride, or jiu jitsu training session.
I’m a regular, so they gave me a deal.
