What can I snack on at night? Have a bad habit long=term!

I’m not sure when it started but it’s embarrassing and disgusting. Almost every night when I watch tv in bed I adore snacking. I’ve gained a Lot of weight doing this. Here are the snacks I’ve eaten: Half a bag of BBQ chips (Ruffles preferred); full bag of Orvill’s popcorn with 3 tablespoons of melted butter; pb&j sandwich; ⅓ a bag of Cheetos; tortilla chips with guacamole and my latest: jalapeno chips. I’ve been doing this for so long it seems normal to me. Now I’m horrified; I somehow now realize if I keep this up I’ll be 200 pounds. I just bought two new scales; luckily, I’m tall. Could you guys help me with substitutes for these so-called foods? Please don’t ask me to sit in a chair and sip water; that is just impossible to contemplate. And no; I do not get crumbs in the bed. The cravings begin at 7pm when the tv goes on . Can you help me? Thank you.
