I just want to thank everyone who responded. Concentrating on one problem at a time, in order of severity sounds very logical, but I also think that if I was going to be miserable and sick from quitting drugs and then again when trying to quit smoking, I think I would want to just get it all out of my system at one time.
I triage approach makes the most sense. My AS does not want to quit everything all at once.
Thanks - a confused mom
