I keep getting fluid in my mouth, what’s wrong?

In almost all cases it’s the atomizer getting ready to go. As the atomizer starts to burn out, some people inhale hard enough that the atomizer cannot vaporize the liquid fast enough. So one literally sucks the liquid all the way to the mouthpiece just like soda through a straw.

In some cases it could be that the coil is gummed up, preventing the coil from again vaporizing the liquid fast enough for the suction being applied.
