Feeling faint And getting "whities" quite a bit today. Day 5 (or is it 6?) is this normal? I don't feel hungry any more and I think ketosis kicked in a couple of days ago. I don't think I'm under drinking, although I may have yesterday as was out and about frantically running after kids all day and didn't monitor my intake. But I generally sip all day. Could it be a deficiency of something for which I can trya supplement? Or is it just a "first week" thing?
