I didn't have any nausea or morning sickness with my DD#1 and I didn't really have any either with DS#2 (more just nausea and an aversion to eating the 1st tri.).
With DD#1 I literally only got that pukey feeling thew up once and that was my own fault when my good friend who is an exec chef made the most amazing veggie lasagne and I hate almost 1/2 of it, it was so good!
This time however, I got nailed, what I didn't get in my first two pregnancies is coming back to haunt me it seems this time.
But some people are just really lucky, but if you really want some I can try and send you some of mine....
