So I sat down to do my nebs this morning and was noticing that it was VERY slow. And it didn't really sound like it is supposed to. It usually makes a sort of gurgling noise in the cup, from the meds being used. So I unhooked the cup from the tubing...there was still air coming out of the tubing. Then I switched to a different cup, thinking the cup was clogged...well the second cup didnt make any sound, and there was no air coming through.

I haven't read all of the replies but the issue is the compressor. PARI's ProNeb Ultra II (not the regular ULtra) go out quickly.
Just call PARI, tell them you're a CFer, and they'll replace the compressor for free.
It's a well known issue at PARI and I've had mine replaced a billion times.
