Hey Dan, don't discount yourself that way! You should be proud of quitting and just like anything else, you should remember and celebrate your successes! They say nicotene is the hardest of all addictions to break. I believe it too because it's the one thing I haven't been able to do. I don't even get withdrawls from all the pain meds. But cigs are another story so as I say my dear, celebrate it.
Now it could be four years, but time to me blurs by, so much has happened I always seem to be doing something or have to be somewhere. Kind of a crazy life I have, but never boring! So you just make sure you have a celebration party and make sure to invite everyone to it too! LOL, it could be worse I suppose, I could chew instead of smoke lol!
