Thanks for the feedback, all. The book did say it can be a highly individual thing. I apparently need a LOT, at least right now, trying to recover from years of debilitating stress and illness.

Added back in my D3 and my K2 today since I do need those, especially now, in the middle of a snowstorm And I haven't had any tummy trouble, we'll see if I was reacting to the D or just dealing with the bug that was going around.
