Keep it up Graham. I stopped just over 3 years ago, once the first week was over it just got easier by the day. As many others have said you start to get an acute taste of food and drink back. For me it was the taste of a cup of tea - could not stand the taste of it which I found hard to believe after drinking thousands and thousands of cups over the years. Thankfully it only lasted a couple of days and now drink gallons of the stuff. On a more serious note nothing would induce me to have a cigarette again, and besides the extra money means I can buy a bottle of Bacardi whenever I wish (which is often). Good luck.
Regards,
John
