Former nail biter here. I stopped cold turkey when I became a bank teller and people were always looking at my hands. Just ... stopped. That was ... back in the 80's :)
The good news for your new nails is that it's August. Nails and hair grow the fastest late June - August, I believe (but not sure as I learned this a LONG time ago) because of the longer exposure to sunlight (vitamin D). I can attest to the fact that my hair and nails do indeed grow fastest these months.
Also remember Jello being good for nails, but not sure if that is an old wives tail.
