I agree with the acrlyic nails! Up until 8th grade, I chewed mine off like you.. Went and got acrylics for 3 months and ALMOST quit.. I'd let them grow out and when one would break, I just chewed them all off.. 5 years later (freshman in college) I get my nails done faithfully and they look better than the real deal anyway... It's pretty cheap and my nails grow slow, so acrylics do wonders for me! Plus the doggies like 'em better cuz I give good scratches now...
And I've known the guy that does mine for 7 years... I've gone through almost every airbrush he has! lol
