How do you overcome the bad habit of sucking your own lips?

I used to do it sometimes when I was nervous or stressed. One day I noticed myself doing it and decided to pay attention to it to stop. I also created a habit to eat ice and decided to stop. I would say notice what you are doing and make a change. Put your mind to it.

Replace it with a better habit. For example keep a bottle of water with you and have a small sip instead. Or get lip balm that tastes bad.
