I told you about my coworker who is addicted to cocaine. She has tried to come up with every excuse in the book. We are friends, not just coworkers, and I think I finally got her to understand that she is on the verged of losing her job. But I think I made matters worse, not better. She gave up cocaine, but now is snorting Vicodin. She says she just loves the feeling of snorting, and can't go without it. All she has done is change from one vice to another, and I doubt that will make her job any safer.
