Cigarettes

i stopped before 8 years with addiction. It was accidentally. I was walking near drug store and saw "nicotine gum", i had also chest pain so i stopped for a sec and said to myself "why not?". It helped me a lot, first some hours was terrible, then next day was better. Day per day after one month i stopped with this nicotine gum. When i stopped with smoking 20 cigaretes pack was about 0.70 euro, now it's 2.5 euro. It's best thing what i did in my life.
