well done tribal girl. i know how brutally, dreadfully shit benzo wd's can be, having gone though them myself with various benzos, many times.
just chiming in to mention that valerian root can be a useful tool to help kerb the anxiety. However this should be saved for when you're completely done with your taper, as you don't want to mess around with anything GABAergic whilst you're tapering (esp. alcohol).
I found that once I'd taken my last dose of benzos, when the anxiety got too much, a couple of VR capsules tempered the fear a little. Promethazine (Sominex) for when the insomnia was really getting out of hand was also sometimes quite effective.
You sound like you're doing the right thing by living and eating healthily, and doing yoga. Of course ideally if you can bear to do it without the aids i suggested above, your body will restore its natural rhythm faster if you just abstain.
However you do it, good luck!
