E.,
It must be very exciting to have baby #2 on the way!
I experienced all day sickness with my pregnancy, but I followed some advice from my sister-in-law which was: taking my prenatal vitamin before bed (instead of in the morning) and sucking on these herbal things called "sick-o-pops" they have ginger in them which has been known to alleviate nausea. (We found them at motherhood maternity and also at some organic food stores. This worked for me.
I wish you all the best.
