I really like the sugar free! I used to drink the orange which is one of my favorites but it had sugar in it so I stopped drinking it. I enjoy drinking these however I feel after a few hours when it wears off you crash hard and want to sleep. I usually would drink another if I need to keep my energy going. Out of all the energy drinks though I do prefer the Red Bull sugar-free. 

I mean I don't know if I actually need to review this since everyone already knows that Red Bull is the Champaign of energy drinks but I buy Red Bull Energy Drink, Sugar Free my Red Bulls in bulk and at this point I should honestly if they had a loyalty rewards program I would be at the top tier!

My favorite redbull by far! Whenever I need a little pick me up I will swing by the gas station and pick one of these bad boys up. Gives the perfect kick and always readily available. Love that it has zero sugar! To me it's the best tasting redbull I've tried

Everyone these days loves a boost of energy in the mid day. And while I am guilty of over-caffeinated breakfast and lunch times, I have found that switching to one of these vs 3-5 cups of coffee with tons of sugar in the cream lasts longer and keeps me steady

Literally my lifeline. My favorite energy drink HANDS DOWN. It has more of a sour than sweet flavor which I enjoy. Keeps me going on my 24 hour shifts as a paramedic. Definitely a staple for caffeine addicts. Red Bull Energy Drink, Sugar Free Red Bull

This disgusting slop should never be consumed by humans and I'll tell you why: I am a doctor , science is my conscience, good will for man my guide. I conducted blind tests with 12 people. Most of these people were in good health and at least 3 had only months to live . This study was funded by private donors . The first day all participants drank 16 16 oz cans. They were provided no food or beverage that wasn't Red Bull sugar free . The first week went as followed - 3 of the participants passed away and one contracted tuberculosis . That subject was sent off and current whereabouts are unknown and won't hinder the final determination of the tests . One month in and only 2 participants are in moderate health whilst the others have been confined to Emergency Room and in 6 cases , rapid detox in a monitored psychiatric installation for their safety . In conclusion , please use caution and discretion. We used to many drinks and didn't offer any food or vitamins which in hindsight was probably wrong . One is ok, pretty good taste . Recommend to fans only .

I love Red Bull! All kinds but specifically the sugar free when I'm trying to be good while on Keto. Love I have this option as a pick me upper. I take these when I've had a rough night and need to go about my day . This definitely will wake you up . Great stuff

Red Bull Sugar Free is my go to energy drink whenever I'm needing a pick-me-up. I start each day with at least one 12 oz. Red Bull, sometimes two. Great taste and zip. Repeat, continuing customer. Definitely recommend to anybody needing a quick energy boost.

I like to drink this drink, but it doesn't always harm me, if I drink it at night and combine it with alcohol, it makes me want to sleep more. But the taste is very tasty, and I'm glad that there is no sugar in it and you can not count calories and insulin. I would also like to write a review about this drink, which is only gray in color, it is only sugar-free

I'm not a big energy drink lover but I do buy Red Bull. I probably shouldn't say or promote this combination but I will because it's so good together and it's my personal favorite. I buy Red Bull for one reason only and that's to mix with my Malibu coconut rum. It makes for an amazing drink that keeps you going without the funky sugar overload.
