Hello mommies I need help.

I’m on my 8 week or pregnancy and it has been horrible for me. The one and only symptom I been having is nausea and it’s bad like some bad I throw up water and I can’t think about food without gagging I try eating fruit and it doesn’t really work, every thing with slight sugar or syrup my body hates it and I have even tried drinking some water with cranberry juice but I throw up the sugar from the juice. It’s become so bad that I am extremely nauseas and haven’t really had a meal or anything without throwing it up. I try to sleep so I don’t feel it but as soon as a wake up I feel like I’m gonna throw up. My doctor has given me zofran for nausea but It doesn’t really help. Has anyone felt extremely nauseas during their first trimester or any trimester if so, what did you ladies do to feel better I would really love your guy’s advice and opinion. I feel helpless and don’t know what to do anymore . Please help!
