I'm curious if the change in weather affects your TBI. I find the season change a dilly for all things associated with inflammation for me, including head injuries. I've had a bit of a struggle, myself, including sleep disruptions. I've also found 'dilly' to be a great substitution for cussing. 😁 (IRL, I don't use substitutions as much as I probably should. If you don't tell, nobody in my neck of the woods will be any wiser.)
