Oh my goodness, I would be in agony in your position!! I hope you get your call soon! That is so long!
First time I heard that one. Were yo dilated any when you drank definitely about to try that.
Have you ever heard of cumin tea?? Its 8oz of boiling water and 1 tbsp of cumin and you drink that and it will start labor. I did it when I tried for my vba2c and I went into labor 2 hrs later thanking it would not work but it did :)
