Yes, of course. You are not doomed to a life of total gambling addiction for the rest of your life, and it's possible to treat it to get rid of the addiction. 

If you have a serious gambling addiction, then my first tip would be to visit a doctor or other health care professional to get help. For many people the addiction has roots in psychological issues, so psychotherapy and things like that could really help with the treatment. 

I also noticed that you used the word "control" instead of something like "stop" or "get rid of", which is interesting. It would be a lot more difficult to have a controlled gambling habit if you are a recovering addict than it would be to just quit it all together. For most people, it's very easy to fall back into old habits. So most people have to quit 100 % to get rid of their addiction, but I suppose some people might be comfortable having a normal gambling level after the treatment.
