Replying to Chiropractors: What are your opinions of them?

So Ive been having extremely bad lower back pain for the majority of my life. I have seen traditional doctors for this problem many times. Until recently the only support they have provided is through Opiates and muscle relaxers. As I am fairly in tune with the notion that the traditional medical system is broken and if you go to the dr you should only expect a pill or a proposition to do surgery I decided to look for alternatives. I saw a chiropractor for the first time this week and after reviewing my xrays and doing some research of my own, I kindof feel like they have a bad rap. Their theory that the nervous system and the spine are extremely critical in wellness seems well grounded. I was alligned for the first and second time over the past 3 days and I feel much better. Before I continue I am getting advice from different people (some swear by them some say run away from them). So I come to you NS'ers. What is your feeling and experiences about them. LETS HERE IT!!!
