I am a nibbler, not really a biter. But my nails are truely pants! Far too soft and they split and shread all the time.
My hub paid for me to have a full set of acrylics done for my 40th and I loved them. Only went for frech polish finish, nothing too bright, didn't want to draw too much attention to my podgey little hands!
I loved having them, kept them for 4 months and missed them when I gave them up!
For me my 'bad' habit it is... I am a confirmed hair twiddler, especailly when my hair is freshly washed and soft, although happy to 'twiddle' at anytime really
