Memory and medicine don't mix!

It is so odd how I can remember so much from before treatment.....seems like since I started, I forget things all the time! Events I have been to before - I could tell you all the details; now....they are so foggy. I am having trouble remembering who I have responded to in emails, what phone calls I have returned, who's order I need to deliver, What time my appointment is, which meds I have taken and on which days. I swear I would lose my head if it weren't attached!
