How do I stop?! I've tried everything (foul-tasting goop, regular manicures, willpower) but as soon as my nails reach a decent length I bite them all off - not down to the quick, but enough that they look uneven and horrid.
I'd consider getting acrylics but the only time I've had them before, they were too long and got in the way of typing, playing the piano etc.
Giving up smoking was easier...
