If addiction normally happens out of one's consciousness, then a gambler is supposed to be evaluating their gambling lifestyle once in a while to make sure that they are still in good conduct. In everything that someone is doing, self-reflection is very important. I don't know about others, but for me in particular, I do something at a time and I think about it all to see if it was really the right thing to do or not, and if I realize I have been doing the wrong thing all the while, then I will just retrace and put myself in place.
