remedies?

I have terrible morning sickness but it doesn't leave ever. I feel totally sick all day long. With Chase I got zofran but because we're moving and switching insurance companies I'm nervous to see a doctor. So my two questions are:
1) if I have insurance here in arizona but were moving back to nevada and our insurance is switching, could the new insurance not accept me if i'm already pregnant?
2) what are some remedies for morning sickness? So far the only thing that works for me is a diet coke and mcdonalds french fries but i really don't want to gain 100lbs so help!!!!

what we go through for babies, but we couldn't be more excited. I may not have a job or lots of money to contribute to charities, but I think the best way to contribute to society is by bringing children into this world and loving them and teaching them to be good people.
