that's not for cervical rippening - well not really. It tends to be a harsh way to force the cervix open (literally it abruptly forces the cervix from its current dilation to 4cm) It's also a very old school method that is not used by many doctors now, at least not outside military hospitals (not sure why, but it's very popular with military trained doctors) Not every hospital "allows" it, I know ours does not allow doing the foley dilation. Another option might be cervidil cervical rippening - its not nearly as effective as cytotec, but people in general seem more intellectually comfortable with it.
I also found my "self induction" recipe. I shared this with a co-worker and she too ended up coming in at 8cm just before her induction date. I thought I would share what I wrote to her. This is by no means an official recommendation and I take no responsibility for any outcomes related to how you use this. I simply thought I would share this - it is no different then what googled on the internet just gimme one moment
