If you experiment, you may find that one tablespoon of yeast is more than you 
need.  I use one teaspoon against 2 cups of sugar.  This may also be the reason 
your yeast went into overdrive.

I'm not sure whether it extends the life or not.  I find that it seems to 
stabilize the CO2 output over the life of the generator mix.  It does not 
prevent the white fluff (bacteria) in the reactor/diffuser.
