I haven't quit smoking yet, but I've cut my smoking in half, and for me that's almost like NOT smoking. You see, I am a smoking fiend. I mean, I have been smoking at LEAST 2 packs a day, sometimes almost 3 packs a day. I have now cut it down to 1 pack, and believe me, even I notice a major difference in my breathing, and in stuff breaking up in my lungs. When I get comfortable with smoking 1 pack, then I plan to go down to a half a pack, and so on. I tried to cold turkey method, and all I did was think about cigarettes 24/7. I couldn't enjoy anything in life. I hope this way will work for me. Even if I don't quit all of the way, if I can cut down to 10 cigarettes or less a day, I'll be happy.
