Winding down on day 16. Yesterday I was around my smoking friends who were kicking out second hand like it was their job. I also had a beer. Still going strong despite the temptations which I am proud of. Still running my 1.5 mile every other day. I don't have anymore soreness from my runs so maybe in a week ill kick it up to 2 mile runs. Get intense cravings from time to time but they are very short in duration. So far so good. If you're in the same boat as me stay with it, we are well on our way to getting out of this tunnel.
