I probably would go with the tea route myself… If I want to consume something but I am not hungry (and I am good so I really don’t eat some food), I drink tea or coffee. Or carbonated water, it’s always fun to me…
I never had this tv/movie snacking, it’s very weird to me. I watch something, why would I eat? I like to focus on my precious food. And whatever I watch, that needs attention too. The only exception happened with peanut and some not too important relaxing video watching but my peanuts lasted 1-2 mins and I went back to my coffee (I drink coffee at 2am as well, it doesn’t matter to me as far as I know. but I usually stop it around 10pm, I am a thirsty one at night so I drink a lot of water).
Something else that would work for me: being very, very, very full so eating is simply out of question, no matter what. I like eating, I have an overeating past (but I was often hungry and now I am very rarely so), little food makes no sense to me and food is one of my most important joys and I find this perfectly normal - but if I am completely full, my desire to eat turns off. Right food choices, bigger, very delicious meals - and I don’t get tempted for a long time, zero willpower is needed.
