I can relate.
My nemesis is on TV. To be honest, I am a little bitter about it, so when I see the adverts for the show it does stir up some negative feelings. I can call these feelings potential triggers.
But everything negative in my life can be a potential trigger. From financial worries to my car breaking down, they are all potential triggers, so I have to deal with them all in the same way.
I deal with triggers by remembering what alcohol did to me, and also by acknowledging what I have achieved since I have quit. I tell myself that if I succumb to cravings, I will rapidly lose all I have gained, and descend into the hell where I was living 6 months ago.
I do try to avoid the TV show in question, but if I see something about it, I try to focus on my own successes, and not dwell on the TV for too long.
