"I lost/forgot some of my vocabulary"

This was/is awful. Pausing, staring at the ceiling, giving up and trying to put together inadequate words to get the meaning across. Get frustrated and just give up on whatever I was trying to say.

Yes, muscle aches, but only in the beginning.

Reading news or technical articles is difficult, but reading books that I can really get into stayed.

Trade offs and maybe only temporary for you. There are always other meds to try.

Good luck.
