When to jump to zero mg effexor? (and being patient!)

I have been weaning off effexor er for a year, and am down to 8.1mg (weighing beads). At what point is it safe/recommended to jump to zero? I have seen different recommendations by different experts (Sorenson, Horowitz).
Also, I'm having such a tough time with the amount of time this is taking. How can I wrap my brain around it and be more patient? I feel like I'm just missing my life.
