What to do when have motion sickness and barely can eat?

Meagan • I am happily married to my husband.
I am 6 weeks and all I eat is crackers,doritos, apples, just snack stuff. I really haven't been able to eat a meal. I eat chicken noodles as well and suck on fresh lemons. I haven't called my doctor yet about nausea medicine. I was hoping to find relief some kind other way if possible. I just get that feel where I want to puke but nothing comes out. I sip on water and sprite all throughout the day.
