I quit on August 26, 2013 when I had my heart attack. I haven't had a smoke since but I have to be honest and say that I still get the urge almost every day. It's not easy to stop but you do not want to go down the road that Krusty did or that I did. I didn't require a bypass but did spend 11 days in a coma, dropped over 50 pounds and my heart capacity is now at 20% and will never get any stronger. My stamina is about where my heart capacity is and even a short walk will leave me catching my breath.
I now have to keep my liquid intake below 1.5 liters a day because my heart is not strong enough to keep fluid from building up in my lungs and I could develop pneumonia almost instantly if I'm not careful.
It will never be easy and you will get the occasional urge for the rest of your life. But you will have a life! A healthy life. Food will taste better. Air will taste fresher. And by quitting now, your health will only get better, you will only get stronger. You will never have any regrets.
You CAN and you WILL get through it. We all believe in you, you just have to believe in yourself!!!
