Cytotec induce labor pros and cons

Alexis
Hi,
My Dr. is scheduling my induction and talked about using Cytotec pill form vaginally. Has anyone been induced this way if so can you share your experience please.
Iv only heard of pitocin as a more common method but he thinks the pill would work better since I'm already 3cm dilated 100% effaced but not having long enough contractions. They last about 2-3hour from 2-4min apart throughout the day and into the night but they stop for about a few hours inbetween.
