Kevin,
Reading your story reminds me so much of me.I've been thinking a lot lately about how I use to buy cigars (Tijuana Smalls) at the store across the street from the bus stop,the walk home smoking them.I was still in elementary school,don't remember what grade.I was a daily smoker throughout high school,we had a smoking area then and always had to burn one between classes.For the last 30 years,I was a 3 pack a day smoker,I and can attest to the fact that it's a tough addiction to kick.
In about one month,it will be a year since if found out I had single cell lung cancer.I smoked all through out chemo and radiation therapy.
e-cigs are the only thing that got me off the butts.I used them and analogs for about the last 3-4 months of smoking,the just decided it was time to give them up.
The doctors never said smoking caused my cancer,and I never ask.Figured it didn't really matter if they did,but no doubt was the cause.
I had a CT scan 3 weeks ago and appear to be cancer free.The last on before showed a little scar tissue,this past one nothing.
It's been not quite a year since I had to start on chemo,I'm just within the last couple months feeling normal again.It's a brutal experience I don't wish on anyone.
So stick with it,you can do it ! And best of luck to you.......Kent
