After 12 smoke-free days, your body is already healing - your
circulation has improved and your lung function is 30% better than
when you smoked.
Right now, try this: Take 4 deep breaths (4 counts in, 6 counts out).
Then step outside for 2 minutes of fresh air - the same time you'd
take for a cigarette break, but this one heals your lungs instead.
This stress will pass in the next hour once you tackle that first
task. Your colleagues will see you as someone who handles pressure
without depending on cigarettes. That's the leader you're becoming.
Check back with me in 30 minutes - I'll have a celebration ready
when you get through this without smoking."let socialSituation = CurrentSituation(

Your friends might smoke, but you're the one who's going home tonight

Here's what to do RIGHT NOW:
1. Order a sparkling water with lime - keep your hands busy
2. Step outside for 3 minutes, text me how you feel
3. Remember: you chose to quit because you want to run that
half-marathon without wheezing
Your craving is peaking right now, but in 5 minutes it'll drop
by half. By the time you get home (around midnight), you'll be
proud instead of regretful.
Text me when you leave the bar smoke-free - I'll be waiting
with your victory message 🎉"- Crisis Intervention Coaching (highest priority)
