I am tired a lot. (If I was not from Minnesota, I might have typed "exhausted all the time." But.) I am not more fuzzy-brained than normal when I'm not in the really tired parts of my day, but napping is a possibility now when it really isn't "normally." I don't manage to sleep more at night, because my waking is generally controlled by hunger, but I do sometimes need a nap in the mid-morning or the mid-afternoon these days. And sometimes I even get one.

And yah, the vertigo is exhausting, but in some ways the bike factor helps with that, because it brings the kinds of exhaustion in line with each other, if that makes sense. The vertigo is mentally exhausting and exhausting in some very physical ways, but "intense aerobic exercise" is not on the list.

(When something goes on for more than a year, it's hard to refer back to personal norms with any degree of confidence any more. Hence the quotation marks.)
