During my high school years, I suffered a bad accident. My right forearm was pretty much shattered, almost amputated. For about a week after all the surgeries, I was on Vicodin 24/7. Just from that, I was addicted. The withdrawal was miserable, and obviously came at the worst possible time.
That one week with Vicodin continues to have profound effects on my life, even now that I'm in my 30s. My fear of addiction convinced me to stay away from all drugs and even drinking. I socialized with people who didn't drink, and found activities that didn't involve partying. All of my social groups and hobbies, to this day, are the legacy of my total adult sobriety. I can't even imagine who I'd be if I didn't have that awful experience with Vicodin.
