Grab that executive function when it makes an appearance, I say.
You have to ride that wave of executive function as far as it will take you. Pro tip: don't sit down. Sitting down derails the whole thing.
Aw Tim, that's rough. I'm sorry you guys are navigating this.
He went to the ER yesterday for 2 bags of fluids after he blacked out briefly in the hallway to the bathroom at 3 am Saturday night. That was exciting. I woke up to a loud ker-thud, immediately thought "WTF did the cat just knock over," rolled over in bed, realized Tim was not in bed and quickly put 2 and 2 together. As he explained later, "I started seeing spots and thought I should lean against the door frame [editor's note: not a solid, closed door; the door FRAME. but in his defense, it was 3 am and his BP was probably like 20/4], and then I was on the ground." So as near as he can tell, he blacked out for maybe a few seconds. By the time I got to him, he was conscious, just fuzzy.
Sunday morning he called the cancer center's on-call weekend line, and they were like, yeah, please get your ass to the ER. And the ER doctor concluded it was just dehydration. This is after he got a bag of fluids on Friday. (Looks like he should have gotten 2 bags.) After the ER gave him 2 bags of fluids and all his tests came back fine, his BP was in the triple digits and they cut him loose. He really needs a better system for staying hydrated.
