Sugar Free Red Bull has kind of become my little go‑to boost when I’m dragging. The 8.4 oz can is the perfect amount for me just enough to wake me up and get me moving without feeling overcaffeinated. The taste is actually pretty smooth for a sugar free drink, and it doesn’t leave that weird aftertaste a lot of others do. I like that it gives me some energy without loading me up with sugar or a bu anonymous · walmart.com

Over the years, Red Bull just didn't seem over the years, Red Bull just didn’t seem to be doing it for me anymore. At their current price point, it started to become a burden so I started to look at other options. Rockstar comes in at almost double caffeine as a larger redbull. The taste is great, and man do they work. And most of the time you can find them for a dollar a piece. It’s a no Brainer Gabriel · walmart.com
