Picture this: You're halfway to work, coffee in one hand, vape in the other. You take a pull and instead of smooth vapor, you get a wet gurgle and a mouthful of e-liquid. Annoying, right? I've seen this happen on commutes more times than I can count. The usual suspects: cold morning air causes condensation inside the mouthpiece, or you've chain-vaped and flooded the coil. Either way, it's fixable in most cases—but not always.
