Many years ago I was a 2 a day Red Bull guy. I chose to back way off the caffeine in recent years for a number of reasons including adrenal stress.
Pre energy drinks it was Vivarin or No-Doz, or one of the two smashed to dust and shaken into a gatorade.
BUT… work is so slow with the quarantine I had to hit up a BANG or a Reign once in a while.
One made me feel like I could run through a wall. Not sure about sticking with any of these once this is over
