If you are completely against medication, there are a lot of morning sickness remedies
that either work or don't work, so you'll just have to test them out yourself and find what does the trick for you. There are SeaBands wrist cuffs (sold at pharmacies). Ginger, sucking on lemons or lemon drops, clear sodas, etc. etc. Of these, only lemon drops helped me, but tore up my mouth from sucking on them all day.
