I do kill my consciousness every night to get some sleep (and for a surgery or two), and it felt weird as a kid (I remember wondering who or what would wake up in the morning) but now I am used to it. Persistence of memory helps a lot, and is probably the real thing that people worry about when thinking about cloning/uploading/teleporting. We identify ourselves from what we remember as familiar, which is why dementia is so awful. It's not like our consciousness somehow exists in the past, present, and future all at once as a single object; we are always migrating with the present into a new experience and whether that is precisely at the time or place we expect it to be doesn't matter in the long run. An alarm clock or light streaming in the window teleports me from last night without any conscious choice of mine.
