I gave up drinking first,then in 1999 I was told I needed a triple by-pass.I was told I had to quit smoking or the operation would be pointless
I didn't want to quit at that time.Although I had tried many times before.
This time I finished the carton I had, cutting down over a few days,then switched to gum for a few months and managed to stop.That was 13 years ago.Other times I'd tried cold turkey and managed to go a few weeks some times but always went back to it.As someone else said,don't quit quitting.
keep trying and you'll get there.It's the best thing I've done healthwise
