Congrats on a year..Im'a still smoking but sure wouldn't mind quitting If'n I didn't think that the world would be a really unsafe place if I didn't have that pop-off valve as a go to!
If you're thinking about it, just do it. I 'thought' about it for years.. those have a way of turning from a few years to tens of years.
There's a lot of ways to have a 'cool down' that a smoke gives you. For me, I walk around the block (or a few blocks) did the trick. The nicotine (for me) wasn't the cool down.. it was taking myself out of whatever was pissing me off at the time.
