I used to be an energy drink addict. I drank two Rockstar a day for several years. I stopped cold turkey and my skin and health in general improved. I also swore off drinking anything in an aluminum can because of the BPA lining. Larger energy drinks have the largest detectable amounts of BPA in them.[1]

These days I drink bulletproof coffee that I make at home and keep in a stainless steel mug. It takes a bit of getting used to, but drinking butter + mct oil+ coffee without sweeteeners is a pretty good way to start the day, IMHO. I feel much healthier because of it and love that it's compatible with the ketogenic diet, which I have lost about 20 lbs doing.
