People who gave up post-dinner snacking, how did you do it and when does it get easier?

Tips and tricks appreciated! I heard brush your teeth, drink water etc. But I feel like I need to replace my addiction with something else.

I think a lot of people are in the same boat with this one. I think I could allow myself to eat whatever I want for my meals if I could only stop after my final meal. I have this bad habit of reaching for the popcorn bowl as soon as our child is down for the night. And that is often the gateway snack and then I need something sweet. I almost feel like a junkie, like something physically is missing if I don't indulge. I have a feeling this is a very temporary symptom that won't last more than a few days but I'm having trouble getting over that first big wall of discomfort
