I had awful morning sickness until 13 weeks or so. I could barely hold anything down, my blood sugar stayed low and I got dizzy quiet often. I'm now 20 weeks and the last few nights I've gotten very nauseous, no vomiting until tonight. Anyone else going thru this? I'm not sure if its "morning" sickness coming back or if I'm actually coming down with something. I never had any morning sickness with baby #1 so this is a whole new world to me.
