Late Night Snacking Habit

I've been keeping a secret for years now. Every night around midnight, I sneak downstairs to grab some ice cream or cookies. It's not like I'm starving; it’s just this weird comfort thing that started when my dad passed away three years ago. The fridge is right there by the couch where we used to watch movies together, and it triggers something in me, so I go for the sweets. My wife knows about it but says nothing because she's too nice. But every time I do it, I feel like such a hypocrite since I'm always telling my kids not to snack late at night. Does anyone else out there have this same kind of comfort food thing? Or am I just nuts?
