Epidural decision

My friend just had a baby, and I'll be TTC within the next 12 months... she had an epidural, but I've decided I don't want one. I might change my mind, but for now its a no. People keep acting like I'm crazy. Yes, childbirth is painful. However, you can be paralyzed by the epidural. It can cause you back pain for the rest of your life. And I've heard that it makes your labor last longer. I'd rather go through the extra pain, than any added hours. I want to hear your opinions of the epidural based on how it made you feel, or why you didn't get one and whether you wish you had or are glad you didnt! Natural birth is a beautiful thing, and I hope to take part in it! (I am not in any way bashing those who have had an epidural. It's a purely personal decision. I'm seeking opinions to help me in my decision for the future)
