When I got down to 4 pills per day, I started breaking pills in
1/2 and lowering more gradually. I usually did 1 in
the a.m., then 4 hours later 1/2, 4 hours later, 1/2, etc., until the p.m. , when I took a whole one. I tapered until I was down to 1 pills per day 1/2 in a.m. and 1/2 in the p.m. I don't know if this really helped the w/d physically so much at this point, but I know that it made it easier for me psychologically.
After I was on 1 pill per day for about 5 days, I stopped.
