a nauseating bad habit which I don't really do anymore
Quitting smoking in 2018, means I sometimes want *a* cigarette. But I know very well that if I had a single cig, I'd be good for a while, and it's just not worth it to buy a pack of cigarettes which will be quite stale by the time I've had 1/2 of the pack.
I suppose if I knew someone who let me bum smokes off them I'd be in trouble, but the only smokers I know are coworkers and that feels off.
