Congrats on your 30 days of quit. I was a ninja dipper for a long time. My wife knew I would chew occasionally, but I was doing it a lot and hiding it from her. She was disappointed when I came clean a few weeks ago and told her that I had basically been dipping for the past year without her knowing. But she supports my quit 110% and asks me every day how I'm feeling etc.
Moral of the story, tell her. You need her help too. She may be pissed for a while, but she will get over it.
You know the drill. Stay focused, post roll, one day at a time.
