Quitting drinking is the best thing I have done with m,y life too. I look at my 7 best friends, and 5 of them I did not know until "The program". The other two were my friends and drinking buddies since school days. One still drinks. Smoking? Fitz, you will quit when you are ready and you will know, don't worry, the time will come, maybe soon that later.
Life is not measured by the number of breaths you take, but by the moments that take your breath away--Wows happen!!!
