Usually have 1 show being binged then a couple of currently airing shows that I'll watch the newest episodes as they release. Sometimes I have more current ones on the go but I try not to as it often ends up feeling like an obligation rather than entertainment when I try to keep up with too many.

As for taking a break to binge something else in the middle? Sometimes but tends to be if I'm getting bored of the first one and usually ends up in it being dropped.
