Laughing gas vs. epidural

I was reading an article about how many woman are choosing to use laughing gas over an epidural, because there's less health risks and it channels pain on a "mental level". 
Have any of you ladies used laughing gas during labor and delivery? Did it control the pain well? How did it make you feel afterwards?
