wish there were more non carbonated options
my absolute favorite energy drinks are the monster rehab collection or the couple no fizz celsius ones, however the taste on the celsius ones often isn't too good but they help me when studying. i stick to sugar free/low sugar at all times which also limits my selection a bit regardless. carbonation often upsets my stomach, and if i buy a drink and plan to carry it in my bag for later its nice to know it wont explode on me when i open it after being jostled around all day.
i just wish this was more common with more flavors other than just tea variants, not complaining too much as i love milder more medicinal tastes but sometimes the super sugary fruity taste is also nice (i genuinely cant name any that are both flat and sugar free in this flavor profile). i know realistically this is unlikely, no reason for the brands to make flat versions of popular flavors just to cater to a tiny market when they already have options (including just leaving it open for hours until it becomes flat lol)
if anyone knows any other fizz free sugar free/low sugar drinks to try that are somewhat easily available in america that would be amazing
