Hi!
I'm struggling with this too! I eat after dinner out of boredom and habit. And if I'm feeling overwhelmed or frustrated, that's a trigger too.
It sure is frustrating!
I've been trying cognitive behavior therapy and it's doing some good--when I use it! Basically it's questioning my negative, unhelpful thoughts. There's a good book called the
Beck Diet Solution that uses it. But any of the cognitive behavior books show how to question thoughts and come up with better solutions. Of course I have to
use the system for it to work

--there's always a catch!
And deep breathing/meditation has helped.
Good luck to us all!
