nausea/vomiting
"Until my doctor gave me Zofran, I was one of the millions of women who suffered terrible morning sickness. It was so bad, in fact, that I couldn't work. The first day I took it, I became dizzy, but the vomiting stopped. The dizziness was gone by the second day. It did cause constipation and I was hungry all the time. By the second trimester, I went off of it and found that my bowel movements returned to normal and my appetite had returned to somewhat normal.

It definitely serves its purpose during the first trimester."
