The grocery store can be a trigger if I happen to walk down the beer aisle. Anger is a trigger for me, stress, boredom, social situations, sunny days...
I have more triggers than I knew about. I tend to romanticize (sp?) alcohol but toward the end of my drinking it wasn't fun anymore, I have to remember that.
Stay strong, I think there will always be some triggers. I try not to let them suck me in.
