I was induced (well labour was technically augmented with syntocinon as my waters had gone and i was having contractions and was 3cm dilated by the time they started the drip) due to baby's heart rate decellerating during contractions on monitoring (6 hours of monitoring during 24 hours and only a half hour period was normal, so we opted for the induction).
I managed it without and drugs, and had a portable iv and wireless monitor so was able to be fully mobile. Being my first I can't say whether the contractions were worse or not, but i did have 5 per 10 mind so not much down time between. I did also have water injections for back labour, but as they're just saline I still consider it to have been a natural, drug free birth minus the synto of course)
It CAN be done. However, if you're being induced "cold" (dcervix not ripe) then it can be a much longer, more difficult process.
Best of luck, I hope you respond well to the induction so can do it without an epi
