Welcome Tim,
Congratulations on the decision. It's definitely a tough decision to make, when that is part of your lifestyle. I made my choice one week to the day (last Monday was my decision to stop as well)
So it's going to be a challenge but everyone on this site has been awesome, supportive and the tools that are provided here are invaluable.
Use them every chance you get, especially when urges come about. Congratulations as well at the decision to get your family started.
