Been tapering, how would you approach "the end" if you were in my position?

We all have our reasons for giving up alcohol and I definitely have mine. About 3 weeks ago I attempted a 7-day taper and while I wasn't completely successful, I made some serious headway. I had been drinking roughly 3/4 of a pint to a pint of vodka almost daily and over the course of 7 days I was able to get myself down to like two shots before I finally had my first "day zero"

Got through Day zero but the following day, the withdrawals weren't very pleasant. I have sought medical advice and was given a prescription of Ativan to use for the withdrawals but I've just been nervous about that. I'm thinking I might have tapered a bit too fast so I've got myself down to maybe two to three shots a day. I've been able to delay them until right before bed and I've even had a few days where I had no drinks, but the days afterwards have been unpleasant. I don't want to take the Ativan while I'm at work because I don't want to be in zombie mode while I'm trying to do office work, interact with customers, or run the business. I've never been the kind of person to drink in the morning or drink at work; I drinking has always been after hours.

If you were in my position, how would you handle it? I myself, I want to be done. I want 100% be done with drinking. I feel dirty now every time I take a drink and even though I get those endorphins and the euphoria, it's not something I want to feel because I prefer to feel how I feel when I'm not under the influence.

Would you try reducing the taper in a few more steps before going sober? Would you cold turkey at with a bit of support? How would you handle us if this was your situation.
