Jowalker, I've got white spots on my nails, too. I've been blaming this on a zinc deficiency, and I've been blaming THAT on PPIs, since I've been losing my hair like crazy as well. I just don't think we absorb nutrients properly while on acid-blockers, so I've started supplementing with calcium, magnesium, zinc and B-12 -- and a few other things. The magnesium calms me down a lot and helps me sleep. Hope the cal/mag works for you.
