I used to bite my nails and I got sore throats all the time. and sometimes they would turn into lung infections. I made myself quit and the sore throats went away. Everytime I caught myself doing it, I just stopped. After awhile, it wasn't a habbit anymore.
put tape on the tops of your fingers, and then you wont be able to, or you could soak the tips of your fingers in Lemon juice (pure) and then when you bite your fingers it will be bitter and you won't want to do it, also, if you cut your finger by biting it, it could, or if you touch a public doorknob or something, you could get sick
Yes you can don't know about you but I do know some people who bite them to the point that they actually draw a little blood if this is your case I suggest you stop because you could get an infection on the area in regards to how to stop well just try your best or use the old tabasco trick pour a little hot sauce and every time you bite your fingers that'll stop you from doing it
Well I'll be straight forward with you... you have got to quit eating unicorns first! Haha, no but really, You just have to be strong and decide to actually do it. No more thinking about it and asking how. It's a self control issue... stay strong, stay focused and just do it. you might find reading a book about breaking habits usefull.
