Hi
AdnilWelcome to bpdfamily

It's good to hear your daughter appears to be doing well 3 weeks in.
To answer to your question there is no alcohol in our home, Adnil it just felt the natural thing to do for us back in 2015, when my DD then 26yrs started alcohol rehabilitation counselling, she made a commitment to herself which I respected and wanted to show my support. Her choices how she socialised and with whom changed and that seems to have been reinforced by DBT that commenced in 2016. Today she will have a drink sometimes when she goes out, or if feeling vulnerable she'll make the conscious choice not to socialise around events eg parties where she knows they'll be drink. She's talked a lot to me about her choices over the time, sought me out to tell me she's not in a good place, therefore not going to a party, last minute apologies and I've been able to validate her choice. I think for DD it's about normalising the environment of no alcohol which can be difficult because it's all around. I will buy wine if we have friends for dinner, or special occasions, any left goes down the sink.
You are right your daughter may not know what's best for her, it's early days, perhaps that's the part of her working it out? How old is your daughter, is she receiving any other treatment? What's she not being honest about?
Welcome again.
