I'm actually more or less out of an art funk at this time - while my finished, digitally done art isn't looking too good, I've done a crazy amount of sketches and that's a pretty damn cool way of keeping the art coming. Course, I do have a tendency to lose pictures so I more or less just staple them together.
Course, actually having something put in front of me and being told to draw this (As of at the moment, doing the concept art for a steampunk game. Fun at times, most times no). But I get through it, one way or another.
Biggest funk I had was for... ooh... about 8 months about a year ago? I don't know, but basically couldn't really be half-arsed to draw anything. Gradually got myself back into drawing in a casual manner, and here I am today, bad but doing good.
Best way for me to get out of a funk is to, I think I've said this before, sketch crazily with reckless abandon and work my way up.
