Please help with morning sickness!

N
So I'm currently 8 weeks 4 days and have had horrible morning sickness since 6 weeks. I'm nauseous 24/7 and am throwing up about 4x a day. I've tried sea bands, preggie pops, crackers, etc and nothing works! What has helped you? And what are your thoughts on prescribed medication for nausea? (Afraid to harm baby)
