I didn't want to say anything in case it went away right away, but: I've had two days of feeling pretty steady now. We're not talking about normal-person levels of steady. We're not even talking about my own pre-Thanksgiving levels of steady. But I'm back to the degree of upright where I can do things like driving safely when necessary.
Also -- and several people can be my witness here -- I'm still being somewhat careful, trying to avoid that dangerous phase where you're feeling better and promptly fall on your face because you forget that better is not the same thing as good.
Still and all. I'll take better, when it's on offer.
