Relentless nausea?

Meredith
Hi everyone!
I'm in week 7 of my first pregnancy and started with the nausea a little over a week ago. It has been nonstop, all day, everyday since it started!
I've tried crackers in the morning, ginger ale, light meals throughout the day.. It's getting to the point where resuming normal activities of ANY kind are out of the question. I'm so emotionally and physically exhausted and I'm not sure what to do!
My Doc has given me an anti nausea Rx but I'm looking for advice on natural stuff! I want to avoid the Rx if possible but I'm feeling like I'm at a dead end. I'm not eating or drinking much of anything and what I do eat/drink comes back up within a matter of hours.. Just concerned about mine and my baby's nutritional status!
Thanks!
