I find I'm drinking gingerale alllllll day long. These may be a nice alternative, but I don't see them anywhere!
Trader Joe's has them - I think they were more in the candy section than in a medicine section. Also, have you tried the ginger capsules? I haven't used them during pregnancy but I did use them on a boat trip once (terrible motion sickness) and they really did help!
ps. - most ginger ale doesn't have real ginger :)
I got mine at hy-vee. I don't know if you have one nearby. But check your grocery store's natural food section's candy.
