I agree that there is no dumb question.
However, I'm not sure the answer.
It all depends if it is a sugar free drink or not. How long it was out of refridgeration as well as the temp it was out in. Furthermore, was in direct sunlight on did it sit in room temperature.
The reason I ask is becuase suger drinks can break down in extreme heat, i.e. sitting in a car all day. Also if they're left sitting in the Kitchen next to a window with direct sunlight it can have an affect on the contents.It's kind of like warmed over beer. Sorta like, not just like.
Consequently the same can be said of a drink that is frozen. The caffeine can crystalize and stick together making "fiber" like strands that are harmless but no less concerning to someone who doesn't know.
Whether you think can or think you can\'t, you\'re probably right!
