I was prescribed codeine for post-surgical pain when I had my wisdom teeth removed a few years back, and then again last September when my toenail was ripped off from a horse incident. The first time I didn't take any beyond one dose, as it made me violent and aggressive, but took them again last year when the pain was so unbearable, I was waking up multiple times per night. The pain didn't subside, even after taking 2. Has anyone else experienced the ineffectiveness, or is it just me?
