Overcoming addictions

I tend to have somewhat of an addictive personality. If I like something, or it helps me with the day to day stress of life, I get hooked. Cigarettes, ice cream, computer chat are some of my addictions. I've tried to quit smoking many, many times with no luck. I made it six months once but it took just one to get me back hooked. Hopefully, I'll be back on that wagon soon. One celebrity who knows a lot about addictions is Robert Downey, Jr., one of the best actors of our time. Sometimes I wonder if the good part of his addiction is the ability to get totally emulsed in his work to bring so many great characters to life.
