I'm pretty sure using these amnesia type drugs is the standard for endoscopies and colonoscopies (versed aka midazolam). You can find horror stories about them online. You can have those procedures done with just propofol or without any sedation but I'm pretty sure they give you versed by default.

I'm sure you can find horror stories for propofol and other drugs, but I'm vastly more uncomfortable with the idea behind intentionally inducing amnesia.
