Two bits of advice for any induction:
Expect a lot of waiting around. It happens quickly for some people, but not for others! I had the pessary, my remaining waters broken (they'd started going two days previously, thus the induction) and the syntocin drip. Whole thing lasted 22 hours (plus the 2 days of waiting with my drippy waters) and I got to the grand total of 3cm dilated! I wasn't too bored since I was having contractions throughout (ineffective ones of course!) but I suspect my other half must have been bored out of his mind - he didn't let on though.
Which brings me to my next point. If you need an induction and it doesn't work, the next step is a c-section. Hopefully it doesn't come to that, but it's a possibility. Frankly if you've been trying for days, it'll probably come as a relief!
That being said, my EMCS was very calm and a good experience.
Some people say it hurts more than spontaneous vb. I don't know since I've only had an induction, but I never had an epidural until I required a full spinal for the CS. If you do feel the need for it, don't be shy about asking. I found diamorphine to be a very effective painkiller, but unfortunately it made me puke a lot (not great during/after a CS!) but not everyone gets that.
Good luck!
