ankylosing spondylitis
"Absolutely changed my life. I got progressively worse until I would become so stiff after sitting for fifteen minutes, I would need help in standing. While nobody who sees me walking would mistake me for an Olympic athlete, I can move about freely and almost without pain. The best thing it gave me was uninterrupted sleep. Until I started taking this med, I could not sleep for more than a few hours without getting up with tears in my eyes from the pain, and walking around while chewing aspirin."
