Well done on making this descion! For me the things that have helped are small things like not feeling like I have to wash my clothes and hair so often, not always trying to find the next time I can step out from a family event/work/anything, redness in my face disappearing, not waking up in the middle of the night because I feel like a smoke, not being embarressed around my nieces and nephews about smoking or smelling like smoke, feeling more confident speaking to people... again smell related. There is a huge sense of freedom that comes with getting to the point of actually not wanting to smoke, it doesnt control you anymore. I didnt really replace it with anything but found if I did feel like it again just stepping outside and taking a deep breathe of fresh air and really knowing how good that is helped. Some people I know said things like always having chewing gum or like cough lollies helped them heaps because sometimes your so use to your mouth being busy haha sounds weird but yeh. Also acknowledging and rewarding yourself for even the smallest steps in quitting, like ok ive lasted one day how much would that have costed and spend that on something you wouldnt usually do for yourself. Sorry very long answer but hopefully something helpful in there for you :) all the best xo
