First of thanks for every suggestion. I slowly over the years became a smoker. I became aware of my addiction. I tried quiting several timer, but every time I would come back to it and smoke even more.
I tried two things so far:
1. Fully stoping to smoke
2. Gradually reducing
But it backfired every time. How did you stop?
If you have gradually stopped and still backfired, I think you did it wrong or you just unable to handle the withdrawal symptoms.
Once you smoked for several months, your lungs have acquired a large amount of tar. Your lungs' natural reaction is to push it out but since you had a lot, your body finds difficulty pushing out. Aside from that your body is cleansing itself from nicotine that may cause several sickness.
Gradually decreasing your intake is better than immediately stopping. Just bear with the withdrawal sickness.
