Wow I don't know how I missed this thread. I hope you are doing OK.
With your permission, doublewhammy, I am going to save this thread and show it to every newbie that somehow thinks he/she can detox on their own. I have been in AA for 6 years and unfortunately your mother's story, while certainly a hard case, is far from unique.
Hang in there and if you need some support, we are here for you.
