Just be responsible with it. I only smoke at night, after I'm done with work, the kid's in bed, etc. It's like my reward for a hard days work. I personally find those highs much more enjoyable than when I was younger and smoking all day long. Maybe waiting for the end of the day doesn't work for you but find something that does. Define when it's ok to smoke and when it isn't (based on your own schedule and values) then stick to it. Most important, let smoking be part of your life but don't let smoking become your life.
