I had a couple of tough days due to some personal problems but did not pick up a cigarette. It is amazing how the brain works. As soon as you have a negative event in your life, your mind wonders off to smoking.That connection is so strong and I think that I might have to fight it after many years of stopping. But even after a month I can honestly say that it is worth it. I used to have pain in my back and chest.Always tried to convince myself that it wasn’t my lungs and it was just my muscles from trainning. But no. It was my lungs and probably my heart too. Now, nothing. I suggest people having difficulties and cravings to take notes of things they notice with their bodies during the process. Like a diary. I started doing that and it really helps noticing the good stuff and prevents you from bouncing back to the old habit. I also want to thank everyone here who replies with very positive comments and share their quit journey. It really does help! Peace ✌️
