I truly do struggle to recall specifics from yesterday or sometimes earlier today, considerably so when it comes to work. I'll be asked how work went and I usually just say "Eh, it was worky.", because I honestly have no fucking clue. I've retained a rough outline of the day. About 20% of it at best. Was that yesterday? Was that today? I have to commit a lot of extra brainpower to recall conversations I had with co-workers (unless they were out of the ordinary or confrontational). I suspect it's due to the monotony of a full-time job, but maybe I have a tumor.
I didn't get enough sleep the other day, and I legit couldn't remember what I had for lunch a few hours earlier. Doesn't help I was drinking the night before.
