Well, I myself used to nail bite. What I have come to learn from my research back then was that there are quite a few solutions, though they differ depending on the person. One such solution is to take some sort of pepper extract or something similar and put it on your nails. Obviously, this will cause a negative reaction whenever you go to put your fingers around your mouth, as it will be hot as hell. A lot of people say that that one worked for them. Though it did not for me. What I did was more effective since I am in the military and am working every day. I just wore a pair of gloves during work and when I slept. This left my hands covered and caused me to be unable to bite my nails for the majority of the day and night.
Hope some of that helped. And if not, I wish you luck.
