I would consider people that are blackout drunk to be p-zombies given this definition. The part of the blackout person other people interact with, their self, simply isn't there - but they are still animated (mostly) like other people with selves. If you are truly blackout drunk I don't think you experience the moment in a traditional sense (a moment from the perspective of a self). There might be an experience there, but it's radically different from what is normally considered subjective experience. The person can have consciousness clinically (as in they show external signs of consciousness) - but their self is not there and their subjective sense is in discontinuity.

The definition of blackout drunk is not remembering what happened. This /could/ simply be a failure to form lasting memories, rather than a loss of 'self-ness.' If we imagine a switch which put a person's long-term memory in read-only mode, would flipping that switch necessarily remove consciousness?

Consider also that brains have different mechanisms for short and longterm memory; functionally, I think we're typically using read-only long-term memory combined with read-write short-term memory, and then writing distillations into long-term memory as-needed. Disabling long-term memory writes in this model may be functionally indistinguishable from a normal operation, at least on shorter time scales.

(For my own part, when I was younger I occasionally got extreeeemely drunk, and would actually flip into some hyper-vigilance around whether I would remember things later; I remember a number of these 'will I remember this later?' moments, though I can't say how many I forgot!)

When my friend found himself walking around in a new place after a complete discontinuity in experience. Was this discontinuity entirely driven by the impairment of lasting memory formation? Seems possible to me. Problem is, I've never experienced this myself - only heard his story from a close friend (repeatedly) and similar stories from others. The stories could be unreliable - but they suggest that the self was offline and came back while the body was still performing complex externally awake actions. Seems p-zombie-like to me.
