I find it interesting that the people trying to do this also want to “mediate” and “have normal sleep hours”.

I think that says a lot about what is contributing to the biting problem. Stress has got to be the #1 cause (I know it was for me). A lack of consistent sleep hours to me indicates an unhealthy lifestyle. I started biting my lips this year (my senior year in college) because I’ve been so stressed about finding work after graduation, trying to get into grad school, trying to finish my senior thesis, etc. And, now that I have 3 job interviews scheduled this week, I can see a light at the end of the tunnel for school, and I’m just ready to let the biting go completely.
