Keeping my resolve

Hello fellow non smokers or trying to quit. Anyway I have smoked for 42 years - I have really struggled to quit smoking in the last five years - in the process of trying to Quit I just ended up using patches as a nicotine aid rather than a quitting aid, so I'm doing it cold turkey this time. I have strong cravings but am allowing them to pass as they are to be expected - there will be pain but there will also be gain - I'm trying to put off having a heart attack or stroke at 55 I'm not ready for that
