Welcome to the forum bro.
I too am a huge dexter fan so the thread title jumped out at me lol.
I was also a ninja dipper for a majority of my nicotine days. I hadn't thought of it in a while so thank you for refreshing my memory about how much of a slave I was. I remember sitting at home with a wad in, waiting for my wife to come home. Every time I heard a car pass it was a race to the window to see if it was her. Or I would purposely lock the deadbolt on the door so I would have to open it so she could come in, giving me enough time to flush the worm dirt and rinse with listorine. Finally, my wife caught me and she was not happy. I stopped for over 100 days on my own, thought I was cured, and tried one more pinch just to feel it "one more time". That one time turned into a can a day within a week and I was back to ninja dipping. My wife caught me again, and like you mentioned about your wife, she determined it had to be up to me to quit. That is what also led me to KTC. Let my mistake be a lesson, we are addicts so there is never just "one more". Your brain will crave that nicotine like a heroin fiend and will try to rationalize why you should throw in another pinch. Come on here, vent it out, and we will help you through it.
The next few days will be the worst of it. You will enter the fog and feel like crap, but it will pass. You have a whole network of quitters that have experienced everything you will go through so use it to your advantage. Remember, one probem + nicotine = 2 problems. This system has helped thousands and it will help you if you let it. So drink the Kool-aid and let's quit today!
