Wow! I didn't expect responses this quickly. thanks everyone for your comments.
Still Waters, I'm not sure what to do if she doesn't agree with me. I think it will be hard for her to deny she's drinking too much as I've been accumulating proof. She may deny she has a problem though.
How did this start ?. Is she depressed/stressed and turned to alcohol for relief ? We used to make our own wine from those kits you can buy at Costco. Is it because alcohol was too readily available and that it started out as a harmless drink after work ?
wish me luck.
