If all you were seeking help for was how to stop biting your nails then I would go ahead and try some of the advice here (I had no idea nail biting was such a common habit!) but if you're looking at multiple addictions or compulsive behaviors then I would seek the advice of a medical professional.
We can give you all the anecdotal advice in the world but unless you address the underlying issues I don't know that much will get done and one behavior might be substituted for another.

Good luck.
