does sight reading still count as sight reading, when you sight read a piece, then come back to it 6 months later and "sight read" the same piece?

I feel like doing some, but haven't got any "unsightread" music

It does for me - I can't remember a piece a couple of days after I played it, so it would certainly come very fresh after 6 months.

Not really. Once read for the first time, the unconscious brain remembers even though we do not remember consciously.

Have you got a local music library? Or friends learning the same instrument(s) that you could borrow music from or perhaps swap music with for a short time?

I expect Steve's right that you do unconsciously remember something about a piece you have played only once, but it can certainly feel like sight-reading second time around!

Not quite the same thing, but when I come back to something I've practised, especially piano music that I've fingered, I can usually play it pretty reasonably straight away, but it doesn't seem to work for me with all composers.

Want me to send you some music Izz?! Return my Finzi and I will send some more!

yeah I'm returning it! Am trying to find an envelope

No rush! Send whenever you can!

Let me know what music you want!
