It used to be incredibly good (apart from names), but it's one of the foremost fields where insomnia is noticeably hitting. I used to have great episodic memory, not quite photographic but I could browse through past events in my head and revisit them like a VR experience almost.

I'm starting to have holes in my brain now, though, and I can palpably retain information much less these days. Episodic memory is still decent, but still fuzzier than it used to and I sometimes have gaps. And retaining written and heard information is much harder than it used to be.
