Did you have back pain 6 weeks + after baby? Did it EVER go away? Any tips for dealing with it?

My back still hurts more than it ever did while pregnant. I'm wondering if this just the norm from carrying around an 11 pound baby and all his gear? My back KILLS every night...to the point where its totally miserable unless I take a pain pill. However, I am running out of those and don't really want to be a "user" the rest of my life! Motrin doesn't seem to help. I've never been to a chiropractor or dealt with this kind of thing before, so any tips are appreciated!
