I did until recently. I hadn't smoked a while, and then I smoked an Ultra Buy Light (I normally smoked Camel Lights). LOL, what a disgusting POS of a cigarette, made me realize how much I needed to quit. I've been working almost full time lately, and I've been able to forego smoking by just drinking water and walking out in the sun when I'd normally be puffing.
Only been smoking for maybe a year. I look at old people smoking and I imagine what their lungs look like, and wonder if they could even run a block let alone a few miles. It's not worth it anymore for me, although I think it was before, when I was having anxiety problems.
