I'd go Xanax --> Clonaze because clonazepam is a bit weaker, and use the least you can manage working down.. what you see yourself needing if you started Xanax? Like if 6mg could last, get that down to 2mg by end of the 190 and then go 4mg clonazepam, 2mg, break in halfs for 1mg towards last few days and stop? That's a rough outline how I'd approach this...
you're one week clean too and I wont pry too much, dont mean to patronize at all, but wouldnt it be easier in the end to not have to induce a taper or if you get kind of screwed up wind up going cold turkey? I'm assuming you have a benzo addiction seeing you're getting this gigantic stash suddenly after some clean time. It's been a few hours since you posted so I have a hunch this is done now and if done this isn't going to end very well no matter how you cut it. Have major meth and alcohol problem myself and building stashes onto benders onto crashes has pretty much fucked my life.
