Nausea help

I’m doing vitamin B 6 w unisom. I think it may have helped some. But I’m nauseous all day. I’ve had diarrhea in the mornings. I’m eating mostly carbs lol. What foods r helping u? Today I’ve been thinking about fresh cut lemons. Would that help? I’ve actually lost about 5 lbs in the last few weeks (I’m only 7 weeks. But w twins so there’s that 🤦🏼‍♀️).
