Myself too does the same, but this went out of my control. As a result I've lost big depositing and gambling. This way I was in big debt and now I'm feeling bad for what I've done. I've shared my story on a separate post Be a Responsible Gambler. Even after this incident I keep on losing every week what I earn from campaign. 
Oh, this is sad. I hope your losses are limited only to earnings from the signature campaign now. What game do you prefer to play? Maybe you should install a casino simulator and play for free, maybe this will help you quell your passion for gambling and you will start saving at least what you earn from a signature campaign?
