Walking epidural

Just curious how your experience was? I've given birth twice before but both were with the full, "regular" epidural and I'm interested in a different route with this birth. I couldn't feel when to push either time and that drove me crazy! Ideally I would like to be more mobile during labor and even try a different birthing position. I'm a huge wimp when it comes to pain. With my first, I was admitted at only 3cm dilated and my second I made it to 5cm before I went to the hospital. I'm not 100% or even 75% sure what exactly I want yet but I would LOVE to hear about your experiences. (If you didn't have the walking epidural but had a different experience than the traditional, please comment as well!)
