All good advice from all our friends above. This is my opinion of how important the mind set is to quitting.
I think the chances of staying quit increase if you identify the core nugget that motivated you to quit in the first place. It needs to be nurtured and remembered but most importantly of all, RESPECTED. It deserves to be to the highest degree.
That thought that we all had on here, at some point, was our mind at its finest and most lucid. It was a little stroke of genius amidst our mundane day to day thoughts.
So, are we going to let a filthy, expensive and deadly tube of transient relief from an addiction win over that pure and honourable moment of clarity and truth we experienced?
NO and again NO!
In my particular case it was thought of potentially losing my leg due to claudication. It was a total no-brainer so when I was told it was getting worse five months ago, I quit the following day. It is now improving with every breath of fresh air I take.
Good luck.
