Nauseous 24/7

I'm currently 10 weeks pregnant and vomiting is getting worse each week. I can barely eat and if i do drink half a glass of juice for brunch, it will all come out instantly. I'm having trouble to take folic acid in the morning because of this and I'm clueless as to what else would work for me at this stage. I feel like my tummy is shouting for food but whatever goes into my mouth comes out within 5 minutes. Anyone can help? ??
