I dunno if all ADHD is exactly like yours, but I doubt it. Your version sounds pretty hellish, to put it lightly.
Good info though, thanks for deeming us worthy of your time (not sarcastically) and sharing your experience. Pretty eye opening for us neurotypicals.
Google seems to have set their nest protect units to need six lithium AA non-rechargeable cells. Which is 1.8v, not 1.5v. You put in completely fresh batteries verified with a multimeter at above 1.5v (1.58v iirc) and they’ll complain about it.
I bought lithium rechargeable and they’re 1.5v. Which seems reasonable. I wish all of ‘em would be one standard.
Feels instead like we have AA-, AA, and AA+.
