How to help constant nausea?

Happy Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> everyone! I’m currently 5w6d pregnant and yesterday and today I’ve been having a constant nausea and almost vomited three times. I hate this feeling so much and I want it to go away. I have dinner tonight with the family who don’t know I’m pregnant yet, I have a gift prepared for tomorrow to tell them. I’ve tried ginger to help my nausea but it only works on me for occasional nausea. I want to eat good food tonight y’all... what are some ways to help with constant nausea?? thanks in advance and have a happy holiday
