This is just the basics, but anyone should be aware of it:
Budget: set it BEFORE you start gambling and stick to it.
Have a break from time to time, it is important to let your brain stop and consider.
Avoid drugs / drink as much as possible, they will make you loose some control innevitably.
Seek help if you feel you are no longer in control. Make a phone call to a friend or go out and speak with someone.
Anything else anyone can think of? Like... read this post before gambling?

This is really good. Addicted gamblers need this to help themselves because they have to control themselves whenever they are in the hot seat. On the budget, they should set it base on their salary in the weekly or monthly basis. The drugs and alcohol drinking will need a special counseling committee for them because they take them to motivate their spirits.
In addition they need to rest under a tree or flowers with soft drink to think how to solve the hard puzzles. As you said, they need to relax and eat good food dress well and look good and go to event place and dance with friends
