Realm: Medical - Subrealm: Boostered

Just as I was planning to head out to the office one last time, the COVID booster shot that I got last night suddenly hit me like 20 cwt. of bricks. Like, harder than either my first OR second dose. I guess (a) this may be because I mix-n'-matched, (b) at least this means it's working?

I think I'm going to go be flat for a bit.
