unmedicated birth tips

natalie
So I'm currently 28 weeks and I'm planning on having an all natural unmedicated birth at a birthing center. I had my fist son in the hospital and it was an induction plus I had the epidural so I'm completely new to this.  
Has any other mommas had an unmedicated birth after a medicated one? How was it? Were you able to handle the pain better than you expected? What are some techniques that worked for you? As May details as possible wold be amazing!
