Wallo, don't take this the wrong way, but what you're saying now is almost exactly what I was saying about 3 years ago. I'm not saying that you're headed down my path, but I will say it's definitely a possibility.
One day, I asked myself who it was that I was trying to convince in saying things like "I'm not NEARLY as bad as THAT guy" and "if this ever happens again, I'll quit for good." Three years later.. being conscious of my problem all the while.. I'm still struggling.
