1/3 of a year. Wow. Do not think about smoking, do not want one, have moved on and so glad. Right away swore off sweats and adopted aggressive exercise program. I can now jog 3 miles and not be winded. I have lost 15 lbs. and instead of being diabetic my tests are now normal and my doctor says no meds needed. I am 63 years young and feel like I am reborn. One day at a time and. Ever one puff!!!
