Can I freeze fish pie?

[TooTiredtoGoogle]

And if so, do I freeze before baking or after?

i do and i'm not dead.

I freeze it after.

Freeze away - I at'nt dead either.

I do, and have done it many times with no ill effects. I freeze after cooking.

yes, and after - as already said.

and I feel a bit like I am dead due to lack of sleep but likely not actually dead and if I am dead it is not from fish pie as I have not had this for a little while.
