I think quitter means removing the restrictor thing at the tip of the mouthpiece, or in other words the little plate with the tiny hole in it that you draw the vapour
through.
If i'm right, then no, you're not alone. I do it with all my carts. I just
thread a narowish screw in there and pull the thing out. Can't say for certain that it makes any real difference, but I prefer it that way.
