I am 37 now and have smoked since I was about 15. The only time I have succeeded stopping is when I stopped for 9 months or so when I was around 20 and then started again (drinking). I have had enough now and have decided that this really is the time for me to stop. The cost now is outrageous and of course the damage I have done to myself over all that time must be huge.
I know I have been a bit snappy with my wife and kids today but I am sure they know (as I have explained) that it will pass and of course worth it in the end.
24 hours down and counting!
