I've been downing potions all day long and I haven't seen an empty *hic* bottle yet!

Seriously though - i've run all over Serpent Temple looking for an empty flask to put some *ick!* spider juice in...
Can somebody tell me where to find one of these things? I was under the impression it was in the area with the levers/coins,
but i've already opened all of them and no luck.

Thanks!

There should be a couple of empty flasks in the kitchen.
