Hi there -

Yes, most of my nails have the vertical lines. And they're brittle. But unlike yours, mine only grew fast last summer. In the winter they seemed to stop growing at all. The Wall Street Journal's "Personal Journal" section had a health feature yesterday about the human body that was really interesting. They reported that vertical lines in nails can indicate that your health was problematic in the past, like a month or two ago. What's wierd for me is that not all of my nails are like that, and you can see the difference the sympathetic blocks have made on my right hand, my nails on that hand are finally growing again and a few are almost smooth. It's amazing. My left hand is in worse shape, all but one of the nails are deeply ridged and are usually cracked and broken. And my toenails don't seem to grow at all.
