How long does it take to deliver once your labor has been induced?

I have three children and all three were induced. For example my last one, I was induced on the Friday morning and didn't have him until the early hours of Sunday. They give you a drug to give you heavy contractions and stimulate labour, so you could be in alot of pain without being fully dilated, so I suggest an epidural as with that you can get some rest before you have to push, which can I add is painless. Good Luck :-)
