SecondChances, I think that quitting smoking is a good plan.

Quite apart from the $$ involved, smoking is a major risk factor for cardiovascular disease, including "circulation and blood flow" and many other things as well.

Quitting is still a work in progress for me. I used to smoke heavily but am now down to 2-3 ciggies per day. What helped me was nicotine patches, which may be available OTC or on prescription.

Maybe nicotine patches might help you too.
