Help! out of control nausea!

Hi everyone! Pregnant with baby #2 and the "morning" sickness is back in full force. I'm on a vacation with my husband right now and desperate to help my symptoms! My doctor told me I could take Dramamine occasionally but it isn't something I should be taking often, so I'm trying to save it for the long drive parts of our vacation. What can I do in the mean time to ease the nausea? What works/has worked for you?? ETA I am 6 weeks today
