Im so glad to hear that you are right back on track! Way to go
. You only fail when you quit trying. I let my "one more" keep me a full time smoker for many years.
Quitting smoking is hard, but we can do hard things! It helped me when I learned that every time I smoked, it just started the physical craving for the next one... Like a very unpleasant merry go round. Everything I thought about smoking was a big giant lie.
