I just freeze gingerale in waxed-paper cups, lol. I have a finicky stomach so have a lot of old nostrum-tonic tricks that I've read about. And frozen liquids are just soothing as the doctor told me they could be. Another good frozen option for nausea that seems to help me is mint tea with honey. And a favorite, non-frozen, is Angostura bitters in soda with a small amount of sugar.
