I think it would be a mistake not to tell people beforehand. You don't need to make a big deal of it - the A word need not be used...but if you say nothing you'll find yourself in drinking situations and no escape.
Do you think maybe that part of you that thinks maybe you could/might drink might also be holding on to your tongue, DD?
I have to be honest - unless you're really committed to your recovery, this is not a trip I'd make.
I realise that bites - sometimes it's not easy negotiating life and recovery....but I really don't think we have to make it harder - y'know?
