It is not easy my friend. They say quitting inhaling cigarettes is similar to those trying to quit opioids. My dumbass quit smoking over 30 years ago. But then I do smoke cigars, but not inhale. Honestly no inhalation of cigars. Anyhow, a couple years ago during COVID I needed to get back to Vietnam and I always take cigars with me. But I got quarantined twice for 2 weeks, and was smoking the cigars that I had. Worried that I would run out, my dumbass bought a pack of cigarettes in South Korea. Been fighting on and off with cigarettes since then. One of the reasons is that cigarettes in Vietnam are only a dollar a pack. Imagine that? But now I have kicked it again and then inhalation free for over a month. You will really notice the difference in your lungs if you do quit. It doesn't matter how old you are. Good luck my friend.
