Not sure if anyone can relate - but just hope I'm not alone

I used to suffer from hypersomnia, and while I don't spend nearly my entire weekend sleeping, I still feel I sleep too much.
On average I sleep 10PM - 6:30AM, and on weekends, I'll only wake up at around 9AM

I sometimes still feel so tired though - I know I go through a lot of dreams, but very rarely remember them. Is this too much REM sleep that isn't allowing my brain to rest?
I take zopiclone to sleep better, which I now think I'm addicted too, as I think you're only meant to use it for a max of 14 days non-stop, and if I don't take it, I'll wake up recurringly in the middle of the night.
