I definitely relate to biting the skin around the fingernails. I couldn't stand the the extra skin that would pop up and I started pulling and tearing it off. The bleeding would start and my fingers ended up extremely sore. Then I started using nail clippers to clip the skin off and that would happen numerous times a day. I thought maybe I had a skin condition, so I tried various lotions to no avail. Right now, for the last two weeks, I have not allowed myself to pull or clip any skin and it's almost as hard as when I quit drinking. I can see on my fingers where clipping is needed but I think I will just put lotion on and try to distract myself. When my fingers do bleed, there seems to be some comfort for me but I can't stand the sight of it. Sometimes when I modify one behavior, another pops up. Sigh...
