My friend was overdue and miserable and tried this after trying everything else. She had severe cramping, horrible long-lasting diarrhea, and ended up in the er because she got dehydrated and needed to be put on IV fluids. No labor though. She went another week and half but was even more miserable because she felt like she had the stomach flu at 10 mos pregnant. They told her in the er that the dehydration can put you into labor, but that doesn't sound like a safe and healthy way to go into labor, especially if you are hoping to be given what will basically be an emergency C-section at that point.
