I thought I was past those kinds of triggers, as the smell of wine/vodka/tequila/etc makes me heave. But I got a whiff of good dark beer the other day that smelled pretty swell.
The only real 'trigger" I have had to deal with since quitting was the emotional pain brought on by a dating relationship gone south. I just came here to SR, talked it out with The Universe, and just kept telling myself that it would pass.
