What was the last straw for you?

I've been trying to quit for a long time. This year has been my most successful with several 3-7 day breaks, but each one ultimately ended in relapse. The worst part is with every relapse I was smoking more and more as my body tried to make up for what it didn't get. I felt totally out of control, which spurred me to try not to be such a piece of shit, but my main motivator was how my throat constantly hurt. I used to sing and haven't for so long because I'd rather screw up my lining with smoke than do something that brought me joy.

Can anyone else share what pushed them over the edge?
