I quit drinking one time. It has held for 32 years. I quit smoking several times a day for 2 years and 363 days.
It was difficult but I felt achievement for doing so it was a fight.
I was semi crazy for about six days, boss at work asked me please start back.
You may never get cancer but I can Promise COPD.
And you don't want people to think you are influenced by Joe Camel.
After a while you well wonder why did I ever smoke?
So do anything but smoke.
