In my opinion, don't take the zopilcone recreationally. It's a lot like ambien (from what i've read), and when I did ambien in the past I tripped SO hard. I don't even know if it could be called tripping. It was like what I'd imagine schizophrenia would be like. If it's anything like ambien, you'll experience something like this: high levels of amnesia, loss of sense of balance, weird actions and activities, and "drunken" like rambling.
It won't enhance anything IMO. Stay away from using it recreationally.
