Biting my nails. I realized I only did it whenever I was in a public setting/social environment. It may have to do with the fact that I'm an introvert and always feel slightly uneasy in environments with a lot of people, so I guess it was my way of "coping" and "hiding" (my face behind my hand) Now that I'm aware of that, I always make sure I don't do it.
Cracking my neck. I started seeing a chiropractor over winter break at my hometown since I couldn't even fully crack my neck anymore without using my hands, and I was getting daily headaches, and kinda quit cold turkey. I still get neck pain from my sleep positions so on the rare occasion I'll do a slight crack. I want to see a chiropractor here but I need a different HMO.
Now that I'm aware of that, I always make sure I don't do it.
