Hi Bill, if I understand correctly, Aiko is not completely tapered off, so there is no "going back" at this point because she is still using albeit, much less. Is that how you understand it? I think her job was driving her crazy as well. I hope she is able to break the chains of addiction. I, for one, believe there is a tipping point at which one could go either way and we can only hope they reach for the freedom of sobriety.
Thinking about you Bill, hope things get better in your personal life.
