Nausea and acid reflux

I thought as I hit 12 weeks at least the nausea would subside but as time goes on it's getting worse not better. My doctor last appointment said to take care of my reflux that it could be causing me to be nauseous. So I had started taking 2 tums every morning. It has helped a little. I don't feel like my throat is on fire but now its more like I feel like food is stuck in my throat. Sounds odd I know. And being nauseous has gotten worse. I dont feel like tums are helping. Doctor said she could call something in but what are some things you do to help.
