Holy Cow Rita!! - when my AH is using - I do ALL the same things you were doing! ALL but add in sleep with a fire extinguisher next to my head so in case the flames are the in the hallway, I can get to the kids and get them out.
This will be the third week AH is in rehab and it really has been a vacation for me. He keeps saying how proud he is of me for handling all of the family/financial stuff while he's in treatment and I had to remind him, I've been doing it for a long time - he's just never noticed.
There is alot to be said about having some peace huh?
