Answer:
I completely understand about being a teen and sucking your thumb. I did until I was about 12 1/2 or 13. I think the major thing that had to happen for me to stop was to realize my problem. You have to come to the realization that you want to quit. The thing that worked best for me was to wear a glove on my hand when I slept. That was the time when I did it the most. You can wear just a simple light glove that way when you feel like you need to, you realize the glove is on, and that you want to stop.After awhile I felt like I didnt really need to suck my thumb anymore. Now, I don't even understand why I did it in the first place :) as for twirling your hair, try something like wearing your hair in a bun or high ponytail so you don't twirl it as often. Just like the thumb sucking you have to come to the realization that you want to stop, and give it your best shot to try and stop.
