I have the symptom as you after taking new obimin, immediate violent vomitting within an hour after taking it, with or without food, any hour of the day, it doesn't matter. After some research, I noticed some moms saying because it contains iron, some bodies can't stand it. so they switched to prenatal gummies, I did the same and feel 💯 I ordered olly's prenatal vitamin, folic acid and dha combined together..from shopee, 30+ per bottle..totally worth my money!
