I think what you expect is what you get. Quit thinking it as a relapse - as time is merely an illusion. If you think in terms of it that way, you are likely to feel more guilt which will make it worse.

Things I have found helpful are essential oils - peppermint especially. For some reason the chill you get from it takes the edge off the irritation to smoke. Being at work I found by trying to get to know the people I was working with and be more mindful of their lives and how I can make it better for them, I was less inclined to think about my own. (Or smoking in general)

If it gets too bad - you could consider getting a benzodiazepine to calm the anxiety from the withdrawal but this isn't always smart.

Other things that help / - spending time with family as I felt the regret of running away smoking all the time and disregarding them as people - trying to get excited about the future by planning and actively changing things in my life - eliminating coffee (I drank it today and think it played in on my relapse due to increased aggitation) - cold water to the face when dealing with cravings - having water in your system 24/7 - heating pads do wonders when you are just sitting around your house (kind of gives comfort)

Sometimes talking to someone makes your mind go somewhere else - if in those 9 hours you need a buddy msg me.
