hyperemesis gravidarum... does this help with the nausea and vomiting 😩

So I got diagnosed with hyperemesis gravidarum after an ER visit yesterday and being severely dehydrated.

The dr prescribed me something called Bonjesta, but it’s fairly new so my insurance doesn’t cover it and it costs about $360 a bottle.

She told me I could try a cocktail of Unisom and B-6. (She just didn’t tell me an exact dosage)

I’m only 6 weeks so even the thought of taking medicine scares me... is this safe? If so how much and how often should I take them? The b6 tabs are 100mg and the unisom is 25mg.

Thanks so much!
