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?
I'm a light smoker who smoke about 1-3 cigarettes everyday in average. I think everything is fine as long as not too much. Even drinking too much water could treat your kidney's health. I think it's fine if you can reduce your cigarette consumption.
But if you still want to fully quit smoking, you can try my friend's method. Some of my friends are managed to quit smoking after switch to vapor and then fully stop smoking cigarette and vapor. At the beginning, they're addicted to vapor after switched from cigarette but as the time goes by, they got bored to vapor and finally they stop smoking both cigarette and vapor.
