I suspect that 2 tablespoons of yeast is consuming the sugar far too quickly.

I use 2 cups of sugar, 1 teaspoon of yeast, and 1 teaspoon of baking soda.
The baking soda seems to help buffer the pH and keep the reaction rate more
steady.  My CO2 generators usually last from 3 to 4 weeks, depending on room
