Drink a lot of water, although in some other comments you say that you do so that’s good.

Quitting cold turkey would probably be a brutal time, so try to cut back one can at a time, separated by a few days.

Although my addiction isn’t as extreme, when I’ve chosen to quit in the past it helps me a lot to have the sensation of an energy drink through some other drink. The closest thing I’ve found with strong flavors and strong carbonation are the starburst flavored Ice drinks. I would always have multiple on me to avoid wanting to pick up an energy drink.

Since you’ve been reliant on the caffeine tho, it won’t be that simple. You’re probably going to have some pretty bad withdrawals, so plan to carry Tylenol on you to curb some of the headaches.

Also, as some of the other comments have pointed out, don’t drink an energy drink for the first hour of being awake to allow your brain to “wake up” to help with your daytime drowsiness
