That's exactly what I'm taking now... I've even threw up my zofran once or twice... it literally makes you scared to eat or drink anything bc you know what's going to happen.. when I wake up and feel sick... I don't fight it..I'll throw up until the feeling is gone for a while... then I'll take half of the zofran with water waita ewhile then eat a little... but also to thru out the day I take the other half.... them before bed take one more half and I feel great unless I skip a day... so in total I take one and a half in a 24 hours time :)
You can try ginger ale saltines just don't take more meds then prescribed. With my first pregnancy zofran just took the edge off but it didn't work miracles. Try to keep food in your stomach it'll help your stomach to be less upset
