To begin, I don’t have advice for you, sorry to say.
I have never been on diamox but I do have similar experiences with cognitive deficits and motivation. I have tested as a child with a high I.Q. but I often feel so disconnected from the printed page and have to reread. I also have trouble following spoken diaglogue, especially news broadcasts. If I read a story and then hear it on the news it seems to gel better.
It’s quite frustrating. I can fake it pretty well and being an underachiever has been a result. I’ve always done well on tests but it gives me a lot of anxiety. I often wonder if I would have chosen a career with greater responsibilities if it weren’t for these ‘hidden’ difficulties.
I’ve stayed away from having to know great bodies of knowledge.
A magic pill would be nice.
