I think applewakesup hit the nail on the head. I'm not sure I'd even bother trying to make an amends with a sibling who is still a very active alcoholic. The thinking is so distorted even in the sober moments that it may actually open a can of worms and make things worse. Talk to your sponor if you have one. If it were me, I'd leave it alone and wait until she's healthy enough mentally and emotionally to be receptive to an amends. Just my two cents.
