Bad habit

So I have this HORRIBLE habit. I bite my nails all the time. The only time I've ever had nice nails was all three of my pregnancies. I think that because I was so nauseous during my pregnancies, I wanted nothing near my mouth, so I wouldn't bite my nails. I would absolutely LOVE to get over this habit. There's nothing like a well-manicured hand (as I bite my nail).

I've done the fake nails before, and I hate how they completely ruin your nails underneath. They are also super expensive, something I don't have budgeted in my "Julie fund" every month:-) I've tried getting them manicured, thinking if they looked nice I would keep them that way. That lasted maybe a week (better than nothing I guess).

Does anyone have any good suggestions? Anyone? Please help!!!!! I'd love to get over this habit, so I can get on to correcting the next one on my list......ha!
