Giveintowin is correct, as ex smokers the difference becomes we learn how to replace the crutch. We just dont reach for them. When i blew my quit i thought just one wouldnt start me going again and i didnt just go back like that. I had quit on feb 9 2010 and i went back on sept 24th 2012. Basically what happened was i had taken my mother to the DR, she had MS but was in remission and i was told that day her MS was terminal and i was devastated. I wasn't thinking clear at all, i smoked one it made me sick. Smoked again a week later and again i didnt buy a pack just a couple at my friends. After a month of here and there i was back at it. After i tried quitting after moms passing and failed a good 15 times and i mean 3 weeks i smoked, 2 months i smoked etc. Mentally i wasnt myself and not ready to give my friend up. All it takes is that one, just like any addiction and these sites are great as we get reminded. I use a straw that i cut down to the size of a cigg if i ever have the feeling of anxiety and pull on that and it works for me. My mother was a smoker and a heavy smoker that after my father death was 3 packs a day until she turned 63 and was diagnosed with emphysema. Lung cancer is what got my mother and it took me over a year after her death to finally keep my quit again. I hope my story can help anyone in a difficult time to just not pick up that cigg, use the straw a blowpop or whatever works for you.
