I've had 3dc, all induced (2 with the drip, 1 by breaking my waters). I've never had any kind of assisted delivery.
If you have the drip, don't be afraid to ask for an epidural before they start it, if you want one. The contractions the drip produces felt very painful and unnatural to me, but the epidural soon fixed that!
That said, though, my sister had a drip induction with only gas and air. We're all different :)
My last induction was actually amazing. My waters broke at home at 40+2, but I never progressed past 3cm in the following 24hrs, despite regular agonising contractions. 28hrs after my waters broke, they put me on the drip. I was 3cm then. I had the most fantastic mobile epidural (I could still walk, feel the contractions, go to the loo etc but it took the edge off) and 4hrs later I was fully dilated. We waited an hour or so for her head to come down by itself, until the urge to push became irresistible.
DD was born with me kneeling over the back of the bed, in about 5 easy pushes. It was great, although long (waters broke 3.30am Tues, DD born 11.30am Weds). But most of that time was just my body being generally crap at labour. I've never got past 3cm by myself. The induction was the easy part!
Good luck! You'll soon have a lovely snuggly newborn on your chest, making long posts like this take hours to write (thanks, DD!) :o
