Congrats on 100 days! We do not allow alcohol in our home so I can't really relate to that but as others have said, maybe wait until after the holidays and tell your family that you need support right now and you would prefer not to have them drinking around you or in your home. The good news is...if any of your children end up in trouble with alcohol and you are sober....they will have YOU to help them. :-) It will be ok. Just stay sober and try to take it minute by minute if you need to. The holidays are hard for everyone.
I just started a thread about having to go to my in laws for a DRUNK FEST tomorrow! Ugh! Hang in there!
