S.K.
as long as she is getting pedialite i think you just gotta wait it out for the long haul. What did she throw up in the middle of the night??? If she threw up mucous she could have a sinus issue one time my daughter had a bad sinus infection but she had nothing coming out of her nose it was all blocked up in her sinus cavities and would drain down the back of her throat. If it was just dry heaves and a little bile then i would just think its a bug which can last 24-48 hours and after that watch out for milk. One time both my kids couldnt handle milk for a week after their stomach bug or they would throw up again.
