Scratch off addiction working in a gas station ?

3 months ago I got a job at a gas station. When I started there I never, or like once every 2 weeks bought a single $2 crossword scratch off.. now, 3 months later, I'm buying several a shift, and some at different gas stations. And I am scratching them off at work.. a VERY BIG NO NO!!!!! I have to quit doing them or I am going to lose my job, and I love my job. But I can't seem to help myself. My boss has told me that I HAVE to quit playing them or I'm going to be fired and I love my job. I'm not sure how to stop playing tho. I'll get bored and instead of cleaning or doing the million and one other things I could do, I play scratch offs.
