People have done piles successfully. You don't seem to be terribly sensitive with as quickly as you were able to go for most of your taper. I'd probably get a cheap "GEM 20" or similar scale on Amazon and a nail file and weigh out tablet pieces. And you may be able to handle that speed as well given your track record. You just couldn't handle the 50% cut from .125 to .0625, which is understandable. Just pay attention to your symptoms. The recommendation here is always no more than 10% every 10 to 14 days. The BIC recommendation is no more than 10% per month, but, again, you can likely go faster. Just pay attention to your body like you have been doing already.
