I don't know if it was the medication. But at some point the voices stopped making sense.

For example if my care takers wanted to poison me. Why am I still alive? They have fed me for months?

These people trying to kill me. Why haven't they made their move.

I had actually given up on trying to evade my "enemies" and simply waited for them to kill me. But for months they never made thier move. This made me realise that I was delusional.
