Speaking of math, @lizardlady & @~Christina ...

On average, how many days a month would you say you miss out on work (or other activities you once enjoyed) because of your condition?

I used to hardly ever call out.

Now I call out at least 2 - 3 times a month because of pain and/or inability to rest well & the resulting fatigue.

The outdoor things I used to love to do are pretty much non-existent now and I sure do miss them a lot.
