My Zoey will barf yellow bile if I don't feed her shortly after she wakes up. There is no sleep in with us.
So, at night I feed her some veggies before bedtime. Ususally, it is green peas, green beans.
The smell is terrible on her face so I have to either wash her face very well or give her a bath to get rid of the stink.
I think if you start giving her a small meal before bedtime this vomiting will stop.
