Relle - I personally had a rotten experience with induction and have said that they'd have to knock me out before they try to do it again!
However, everyone is different.
My question would be - what if the induction doesn't go as smoothly next time (if you do decide to go down that path?). Being your 3rd, perhaps going into labour on your own won't be as painful and long because your body knows what it is doing (and you know what to expect?).
