Nausea worse in the evenings?

I’ve always been this way with sickness of any kind, but around 7-8 pm I start realllyyyy feeling ill. Of course it has to be the same with morning sickness 🙄 Ive started feeling better throughout the day with b6 and unisom, but in the evenings I get super nauseous and have to take a Zofran or else I’ll throw up (and not stop). I’m hydrating and eating consistently throughout the day, so I’m not sure what else I can do to help with the nausea!😰
