and I concur with the others...You most certainly can NOT shoot too much film. ............Nor can you buy too much, have too much in your kit, your freezer or on your Ebay watch list (my wife would argue most of those points, especially the last).
It's not to be recommended but on a night school course I even managed to put two different speed films in the same tank and was half way through development before realising. The dev times were a couple of mins different but both were salvaged by splitting the difference. OK both were old type Ilford films (HP5 and FP4+) but the negs from both were printable. So if it does ever happen to you, don't despair. You may be OK.
Mind you doing one at a time, avoids all these problems.
