B6/unisom withdrawal

Sabrina • Preggo with #2, trying to enjoy every second!

This is probably going to sound like a weird question. I’ve been taking b6/unisom combo for nausea because my insurance wouldn’t cover Diclegis. If I don’t take it I wake up with a horrible headache and feel hungover and then continue to puke all day. I’m 15 weeks so I feel like the nausea should be ending because this is when it ended with my first. Has anyone else experienced this?
