I never had HG, so have no experience with medications, but I did have morning sickness for the first 16 weeks of my pregnancy. In addition to the ginger, small meals, crackers, etc, I found that certain smells helped me. For me, smelling a fresh cut lemon really helped. I discovered that when I was in a restaurant- the people next to us ordered fish, and I thought I was going to throw up right at the table!! I grabbed a lemon slice, squeezed it, and smelled it, and it worked! I have heard from other moms that rubbing alcohol (not sure about fumes on that one), lavendar oil, Vick's Vapo-Rub, and cinnamon extract worked for them. I know it's just a little short term relief, but I also know that any relief is worthwhile!! Best of luck!!
