Well if you can't control your gambling addiction what you can do instead is find another addiction that is less life threatening like being a smoker or addicted to video games.
with your case, i suggest u focus on gambling to stay away from smoking and games addict, seriously. u can get rid of gambling later.
yeah I think looking for ways to become addicted to another, instead will add to the problem, I agree, it is better focused by avoiding gambling, without adding any other problems
