I edited my post. Thanks for the nudge that made the light go on. Aricept is an acetylcholinesterase inhibitor not an anti-cholinesterase inhibitor. I still have these moments, and one of the side effects of topiramate is worsened memory. (I can handle that if I can function, but sometimes the results are weird.)
I can't tolerate benedryl, period.
Ever.
But I think that it's possible to have higher levels of choline in the brain after chemo without having higher levels of choline in the body. That's been demonstrated with a lot of chemicals that act as neurotransmitters but are also present elsewhere, generally. As choline levels rise, serotonin levels fall. I believe there may be other consequences, but I don't have them to hand.
Exercise didn't help me at all. If I did manage to get myself up and active, it put me down for the count for at least a day or two or more afterward. It was terrible. Now, I'm able to take a daily walk again without a problem, so maybe I'll be able to go back to the gym soon.
The written schedule seems to be the tool of choice. She printed out daily pages from Outlook for me. I resisted because I have Outlook, and I'd rather do everything on the computer, but there's something to be said for a notebook that you can scribble in. You just have to be careful to allow yourself enough time and enough breaks.
