I've been a 3+ pack a day smoker for 35+ years. Haven't had a smoke for 45 hours.

Keep at it! My uncle smoked for 40 years he had a mild heart attack, put the pack down for almost 8 years, his secret every time he feels the urge he gets a lollipop from his pocket. Now he doesn't even need the lollipops! Honestly smoking and drinking will only bring you down health wise and financially. Keep it up!
