Any nausea cures?

I am nauseous 24/7. It’s to the point where I can eat or not eat and it doesn’t matter. I get to the point where i am gagging but don’t actually throw up but it feels like I am going to. I am drinking lots of water, getting sleep, eating healthy, etc. I have tried the sea sickness arm bands (I get severe car sick so I had these already), I have tried to eat every few hours, and tried to workout and relax. Any other tips? Nothing is helping and I am totally miserable. I can barely function throughout the day. My first appointment is Monday and I’m praying my doctor can help. Please help. 🤢
