As WS says, always loosen a truss rod nut before tightening. And you usually don't need much movement at the nut to fix things either.
I always had a slightly higher than average action because i hate buzzing strings but also the way frets can rob you of sustain even if they're not actually buzzing. But I'm mainly playing newer Gretsches made in Japan right now and I'm finding I can get a lower action than I'm used to with them without losing anything.
But if I buy a new guitar I inevitably have to raise the action.
With Gibsons I used to have to always cut the nut slots a little lower too, but the last few have been pretty much perfect so I don't have to do anything other than gently open the slots up a little bit to let the strings move without catching - something every guitar seems to need. And maybe because of where I live it seems that every single guitar I get needs the truss rod loosened a tiny bit.
