> sleeping on phenibut is very restful

Is this just you subjective experience or is it backed by some data or research? For me personally, sleeping after phenibut doesn't feel healthy at all -- in fact I often end up sleeping for 12+ hours unless I have something important to do in the morning, and it's extremely hard to get out of bed every time.

I don't know if it compares to Ambien at all, but my wife takes that and every once in a while I take one to help get to sleep. It gets me to sleep and I stay knocked out, but a long 8 hour sleep with Ambien never seems as good as a "real" 5 hour sleep without it.

Ambien drastically reduces the restorative deep sleep and REM phases of sleep, so you are correct in your assessment. Your brain needs those phases. Long-term use can cause cognitive issues and cancer.
