WELCOME TO SR! It's great to have you here! Most people "lurk", or hang out and read quite a bit before posting. You may have been too, and it's great to see you posting!
Suggestions to new comers often include reading the "stickies" on top of the forum. These can be of great help!
Also, have you tried AlAnon? This is a wonderful, supportive place to augment your time on the SR forum.
Above all, here are the 3 C's that are so important for your well being:
you didn't CAUSE your daughter's alcohol issues
you can't CONTROL it
you can't CURE it
For your own well being, it's best to take care of YOU, and be gentle on yourself. Keep posting... we're glad you're here!
