Honestly dont think there is anything I tried everything and nothing helped. My friend told me they have a gum at walgreens I forgot what its called she said it makes the nausea go away.
I have the same issue, just got out of the hospital with a diagnosis of hyperemersis something. they gave me zofran to help. I haven't eaten food in 4 days, hopefully this helps.
Ask your doc to give you some meds for it and see if they help
Try half of b6 vitamin with half of tab of unisom.. its safe and works miracles ask your doc asap about it ;)
