Luckily for me gambling is now a past thing I used be a passive gambler and always tried my very best to control but as always it seemed impossible , finally I decided to stop gambling but blocking most the gambling sites for few weeks
Now I don't want to earn a single penny from gambling
I am also on the same boat. When I started with gambling, I used to visit those websites daily. I realized that it was affecting my work very much and thus controlled this. Now I play occasionally depending on how much free time I have.
Wise people said it once, utilize your free work in productive chores so you can be productive for yourself and your family. While if someone thinks he might be benefiting himself and his family or country by utilizing his free time in gambling then this is alarming. This is really sensitive for your thinking regarding your contribution for your society being a citizen of your country.
