For what it's worth, I have a problem staying on paleo and it shows daily: 
if I'm on it, my b/p drops to normal levels and when I go off, it rises to 
pathological levels.

HOWEVER, my chiropractor, in relation to a different issue, told me I should 
drink one half my body weight in ounces (that works out to 80 oz or about 6 
bottles of water at 17+ oz. each) per day. So I began doing that and noticed 
that, despite some cheese here and some crackers there and a little peanut 
butter and toast everywhere, my b/p stayed down.

After a couple of days, it dawned on me that that steady low level began 
coincidentally with my vastly increased intake of water.
