<human>: I realized, from [this post] that nail/skin biting can be considered a type of OCD. I've been doing it since elementary school and i'm in college now. The past few years, i've been trying to stop, but I don't think I was serious enough. 

I was kind of awakened by the post because I found a lot of things that ran true. The fact that it can be considered a type of OCD was odd because I do have those urges to bite off the dead skin and long nails. I also have been biting the skin on the inside of my mouth recently. These are all things that the post mentioned.

I may have started in elementary school when I saw my teacher doing it. I'm not really sure, but that's just a thought I had when I was doing this sort of reflection.

I'm sure many other people have had this problem. Is it just a habit or an OCD impulse that will never go away? I've heard success stories of people stopping and I want to be one of them. Does anybody have any success stories that you would like to share? Anybody have any protips?

I'm looking for one of those nail polishes that you can paint on your fingers that taste bad to help me stop biting my skin/nails. It has to be clear, as I am a guy. Also, I need something that I can put on some other parts of my fingers because I chew skin as well.

Can you give me a shortened version of the text?
<bot>: Can anybody recommend a nail polish that you have used and have been successful with to help me stop biting my skin/nails? Links to amazon or something would be useful.
