Spoke to my Dad, he was very receptive and said he was concerned about his drinking too, so he's re-doubling his efforts to stop.
Whether he actually will or not remains to be seen, but I've done what I can so I feel a little more peaceful.
Thanks all, I honestly could not get through this type of thing without you.
Rudy, conrgatulations my friend. I know what you mean about it not being as hard as you thought, I think sometimes when you get into the habit of sobriety weeks can go by without thinking about it. Just keep watching your back!
