The sparkling versions are fantastic
Reviewed in the United States on March 11, 2018
Celsius energy drinks are the only energy drinks I will consume. If you're like me and don't like the typical tastes of other energy drinks (red bull, monster, etc), I would highly recommend trying these. The sparkling versions are the best and I sip on one throughout the day, just 1 as it has so much caffeine and 2 makes me too jittery. However, if you have trouble sleeping, then I wouldn't suggest drinking these for at least 6 - 8 hours before bedtime as it will almost certainly keep you up. The sparkling grape is my favorite, second best is the wild berry, third is the orange. Cola is the absolute worst flavor. Tastes like a generic soda that's been left open to go flat and has lost most of the flavor. The watermelon is okay, but tastes the most artificial. I noticed when I started to perspire or feel warmer than usual, for me, it was working to boost metabolism and burn some calories. These are easy to build up a tolerance to the caffeine and lose some of the energy benefit after 1 - 3 months of daily use. So you might consider skipping a day every now and then to consume a smaller amount of caffeine to scale back on the tolerance and then come back to these for renewed benefit.
