Why do I not remember my K holes?

Last night me and my girlfriend had some fun with MDMA and K. We took mdma first and were bumping it with K throughout the night. Once we got home around 4:30, we did a 80mg line each, now after this I don’t remember anything at all really, just very small patches of memory of me racking up 4 75mg lines and 2 50mg lines and then sniffing them with my girlfriend. These lines were racked up about 30-60 minutes after the initial 80mg line and i literally have very little recollection to what happened. Woke up around 6:20am and me and my girlfriend definitely holed but I don’t remember it at all. Did I do too much? I want to remember my k holes for when I do them in the future.

Also is it normal to literally not remember what you’re doing when on ket. I asked my girlfriend and she said I was literally walking around as normal, talking to her as normal. But i literally don’t remember anything at all after that first 80mg line when we got home.
