>>42298989 (OP)Twilight would be a tea drinker, specifically black or oolong teas that Fluttershy grows for her.
Fluttershy herself however drinks warm diet soda because she doesn't own a fridge and strong energy drinks give her anxiety.
Rarity is on ozempic but loves Alani's after switching from Celcius, and buys it in cases.
Rainbow drinks Reign Energy because its branding is parallel with pre-workouts, and it doesn't have Taurine which makes her fart like crazy.
Applejack drinks coffee with a little creamer and no sugar in the morning with pancakes, occasionally she'll have a Monster energy when they have a large batch of apples but not all the time.
Pinkie doesn't drink shit, energy drinks cost too much and shes poor as fuck. She's one of those that takes caffiene pills from CVS.
