You most certainly are at a point that's reasonable to jump off.
You may experience some w/ds, but they shouldn't be horrific. The doc I Work
ed for at a sub clinic recommended pts tapered down to 0.5mg before jumping off completely, and most who did it that way did fairly well. They usually experienced some level of w/ds, but most managed pretty well.
What kind of "Work
" have you done on your recovery? Attend meetings or any kind of addiction therapy?
