I'm just curious is all, as it seems like a waste of money to me. Now yal don't be afraid to admit that you do, as no one who matters will think less of you for it!

I am guessing in bravely default but the answer is No... What is that thing even used for? I wasn't paying attention during the tutorial...

It refils your SP... obviously!

I've got three available, the max.  I've never used one.

I sure hope not. It refills over time in sleep mode. I'm sure there's the odd sucker out there though..

Suck Punch makes drinks? Where do I this mysterious beverage?

I've not used any, have 3. And if I do need to use them, I'll just wait for a free one... I'm a cheap bastard.

Same here. Well...mostly. I used one when they introduced it, and another for the tutorial quest, but past that, I don't intend to ever use them. 

OT: You can get them for free by putting the 3DS in sleep mode, so I don't see why people would spend their money on them. Maybe there's some random person out there who likes video games but doesn't like to be challenged. Easy mode's too hard. Or something.

Thanks to those who clarified what this even about, I had no clue xD

I thought it was some real life drink.

I'd never use something like that and I'm a little disappointed that Nintendo allowed such practices on their consoles.
