I've avoided the F&F section. Thankfully, I'm not married and I don't have children so I can't really offer any sage advice. However, my father was a serious binge drinker, he would disappear for days on his binge drinking episodes. I knew what was going on starting at three years of age (and that's just what I remember). Needless to say his behavior left an indelible mark on me. Reading those posts would be a little too much for me right now.
Most of all I feel for the children. They have no choice in the matter, and their suffering is incredibly unfair.
I would just remind any of the parents that have an addiction problem or who have spouses with an addiction problem to not be in denial. Your actions are affecting your children. They know what's going on, they are being hurt, even if they are very, very young.
The greatest gift you could give your children is sobriety.
