As a former nail-biter for years, I understand your pain! Luckily, I stopped biting my nails long ago..what finally made me stop was sophomore year of high school, we were ordering our Junior Class rings and I didn't want to have chewed, bloody nasty looking nails when I got the ring. I finally succeeded in stopping that time.
You say you're still a student. Do you mean you are still taking pre-reqs for nursing school
, are you in nursing school and haven't started clinicals or are you in school and in clinicals? I ask this because in our school (and in many that friends attend) we were told on day one, enjoy those acrylic, sculpted, artificial nails now, once we start clinicals you CAN NOT have them on at all..for any reason. We can only have natural nails, no longer than 1/4 inch over the skin, and polish can only be flesh tone, light light pink, or a french mani. I find the allowing of polish only in certain colors laughable. Its silly to say those colors are allowed..what, do those colors deter bacteria?? Do those colors not peel and chip off like the other colors? They allow those colors because you can't SEE it as much when the polish chips, peels off. But, it does, and it can end up on or in a patient just as easily as any other color.
I know that all the places we've done clinicals at, the nurses do the exact opposite of what is insisted upon for us in clinicals..hair up and off the color, no heavy perfumes, and NO artifical nails. I can't tell you how many times I've noticed nurses on the floor with hair all over the place and the nails..oh my! I cannot believe that the nurses can do anything with them. (I have had my nails long, natural nails, and I get to a point where I have to trim them because they are too difficult to do everyday things with. Let alone trying to do treatments, suppositories etc. Not to mention, the potential of scratching the pt.
I guess my best advice, and you know this already, is its best to stop biting. Not just for school but for YOU. Its very unsanitary. Think of all the things you could get on your hands..do you really want to put them in your mouth?
Best of luck, I know, its difficult to stop, but you CAN do it!
