set your computer not visit site which contains gambling,in that case you can surf the net free without thinking that you will enter to gambling again....gambling is not a drug its a hobby, 
I like your suggestion !
But an gambler cannot do this ever. Gambler is really addicted to gambling. Every person have interest in many things. So if we have to quit gambling for food, we should use internet less. Pay attention to different activities than bitcoin gambling. May it effects a gambler !
