My guess is that the strict low-carbing is what is bringing your numbers down, because there's still a fair amount of met in your system & it works especially well when used WITH low-carbing. It isn't dangerous to just stop taking it but it takes a few weeks to build up in your blood stream & it takes a few weeks to completely disappear.
But after 2-3 more weeks, if you can maintain lower without metformin, more power to you - especially since you get the side effects (did you ever try metformin extended release? The XR version usually reduces the side effects). The dosage you were taking is pretty low anyhow.
I also have no doubt that your fall is what caused that spike to 134! That must've been scary. For years I've descended stairs one step at a time, and I don't move to the next one until both feet are firmly planted on one step!
