I've been a 3+ pack a day smoker for 35+ years. Haven't had a smoke for 45 hours.
I’m a non smoker and I have always heard quitting smoking is the hardest thing...or is it quitting MoPars?? LOL....
You can do this...stay tough and beat those cravings! I had a friend who quit and he said he could actually taste food again and didn’t have to use as much ketchup or salt to add flavor! He asked me one time “did really smell like smoke that bad?” I said yes, he felt bad and apologized, he said he didn’t even notice it.
I also have an aunt that has probably smoked for close to 45 years and she quit cold turkey all on her own and is doing awesome, think she’s going on 2 years now. But good for you and for your health! If your wife quits too then it’s even better and will be easier if you do it together....good luck!
