Yes, I have both horizontal & vertical. I’ve had vertical for as long as I can remember. The horizontal just started about 2 months ago. I can remember having white marks on my nails when I was a little girl…. Mom used to say I got them if I told a lie 🙂 haha. They seem to come & go- good to know it’s related to zinc (but scary that I had them as a child). My nails also flatten out when they get long & a few seem to grow downward. I’d say I have Terry’s nails as well.
As far as the liver goes, I have consistently LOW bilirubin and was born jaundice. My cholesterol was a little high for the first time ever last fall.
