Induced by breaking water

Anyone had success with being induced by just breaking your water? I am scheduled to be induced on Monday and doctor wants to try inducing labor by only breaking my water in hopes that we can avoid pitocin. I am dilated 3cm as of last week and 80% effaced. Baby is in 0 station. She has high hopes for this process for me. Just wondering how fast labor will be and if it worked for anyone else! Thanks :)
