That seems very sensible. Have you found any sort of substitute for a morning cup of coffee? When I first stopped consuming caffeine I didn't have any decaf on hand and tried a cup of miso soup in the morning. I love miso soup but it was not a substitute for coffee

Yes. As we know coffee has umpteen chemical compounds. I was still having symptoms with decaf, so until I got a handle on all possible precursors, I opted to forgo all. "Wikipedia: List of chemical compounds in coffee"

10,000 rpm? You need to attach a router to a burr set to get those speeds
