Cheese,
You have done the right thing by coming here . Keep a Positive attitude and a good sense of humor and come here to chat when you need someone to talk too.
It took me 35 years to finally grow a set of balls and quit making excuses for my habits. I gaurantee its not easy,but it does get easier by each craving at a time, or one day at a time.
You can do this and hang tough with the best groups here on site.
