3 days smoke free

Hi everyone, I'm new here....

this is another attempt to stop after 30 years of smoking.  Last year I managed to quit for 6 months after a health scare but during a really stressful time I thought I could have 'just one' and ended up smoking the whole packet and then convinced myself that another packet wouldn't hurt. A year later and I'm still smoking and promising myself that each packet will be the last one I buy. 

I'm on day 3 of quitting right now and and really want to make this the last attempt...I'm so sick of the whole smoking thing, so hoping to get some extra help from this forum and reading other people's stories.
