All math or programming tasks become oddly hard. Something simple that I had done 1000 times before in seconds became a week long project. After I had been on blood thinners for a bit and my mind recovers I sat down at a problem that I couldn’t figure out for six months. 10 minutes later it was done. Had an ER visit were I was getting all questions wrong. Year, president, etc. I knew my answers were wrong. But I didn’t know why, or what they should be.
