Welcome aboard sir.  Your story sounds a lot like a lot of ours, except you are a lot smarter/younger than a lot of us.
For many of us, nicotine was the root of a lot of health problems.  Once you start focusing on yourself instead of getting a fix of something that doesn't even give you a slight buzz anymore, it is amazing how healthy and refreshed you feel.  Quitting will change your whole life.  Sounds lame, but it really will.  If you need a contact or any help at all, don't hesitate to reach out.  There is no better gift that you could give yourself or your family than what you are doing.
