Yep. I did it first time out. As to why...well, being diagnosed with cancer, having your neck cut open from ear to ear, then having complications from the surgery convinced me that smoking was NOT worth what I went through!
I do admit I miss it terribly. At times I pass a smoker on the street and breathe in the smoke and it reminds me of the relaxation I always got from a smoke.
Now, later in life, I have chronic lung problems, probably from my years as a smoker. Again, more reason NOT to smoke.
