It's got sucralose as a sweetener, which I know will make it undrinkable for many of the people on my timeline, but I enjoy the drink, both the salted caramel and the Mexican vanilla
(not counting on it by any means, as that has never happened as long as I've been here, power goes out we all just sit in the dark until it comes back)
That and gas seem to be most people's problem with it, I have noticed either. Xylotol makes me gassy and so I attempt to avoid it on principle
