Daren, seriously dude, you gotta quit... for the sake of your little guy.
I grew up as the only non-smoker in my family. Dad smoked 5 packs a day (Rothmans) and mum was 2-3 packs a day. My sister started at age 14 and my brother age 12.
My siblings still smoke, but my parents quit cold turkey 19 years ago. Imagine for my dad, if you will. He was in the process of losing 80lbs of fat AND he quit his 5 pack a day habit (that he'd had since the 1950s) at the same time. He was NOT fun to be around, but he did it.
How?
My best friend had been driving home from his summer job, after the night shift (like me, working his way through school) and his car got hit by a drunk driver going almost triple the posted speed limit and this a-hole was four times over the legal limit and it was his third DWI offense.
Poor Pete had no idea what happened, and he was in a coma for 18 months. My dad said that he'd quit when Pete came-to and asked him to quit. Miraculously, he did and my dad stuck to his commitment.
Daren... quit man. You can do it!
