I have and it did, at first, but I'm not one to give up on things, so, from time to tim I persist in thinking along such lines. It is difficult to imagine nothing as we and everything around us seem to be composed of quite the opposite...something. Nothing could not be constructed of matter, a more general term for the something that everything is made up of, unless of course it is nothing, but then it wouldn't be something.
Shying away for a bit on what could become a very seemingly circular monologue if allowed to be carried on, I will give you some of my conclusions. I believe in balance and that all things are seeking it, be they conciously aware of it or not. Even down to the atomic level where we could talk about electron shells and such. Even if an atom has a shell filled to its max, however, the atom is still made of matter and is, then, something. What though, if a piece of matter meets its antimatter? What if one meets negative one? What if yin meets yang? Nothing, the ultimate and perfect balance, would, I think, be total nonexistance. Not the most cheerful interpretation, but it's what I've come up with so far.
