Hey Hank - I had similar trouble to what you describe. I'm still finding that I'm watching somewhat familiar episodes of Law and Order that I think I might have seen while undergoing treatment!

I was really worried about going back to work especially when I found that I forgot to fill the dog's water bowl or turn off the stove after I made tea. I was concerned that I really had no business at all even going back to work - but I did, and I struggled and I found that I'd lose my train of thought mid-sentence with no hope whatsoever of the thought coming back to me, I kept lists upon lists and multiple calendars and fretted that I'd never feel like the real ME again. Now, 6 months post treatment, I can honestly tell you that my brain is back! I missed it for a long while though!

When I complained to my MO about my memory he said "you don't want to remember this." There are still some holes in my memory (Law & Order...) but I'm not worried too much about retieving those especially now that I can remember what I did yesterday and where I'm supposed to be tomorrow!
Take care and go easy on yourself!
