This is very "distant" suggestion if you enjoyed Antimemetics, but The Unconsoled by Kazuo Ishiguro is another one of my favourites, and it too explores this idea of unreliable and inconsistent memories, although from a completely different angle.
I consider Recursion by Blake Crouch to be similar, even though I liked Antimemetics much better. I haven't read Crouch's other books, but have heard that Dark Matter is better than Recursion, though it may be less similar to Antimemetics.

Premier work is probably Blindsight but the Sunflower cycle stories are likely easier to start. Like qntm, a lot of his works are online for free:
