But you are right, when i do that my apm starts dropping.
The thing is. If you do stop trying as hard as you can, the chances are high you will lose your advantage pretty quickly again. In ZvT you might killed his pushes very easy. You have lurkers outside of his base and start expanding all over the map. But a few nice drops at place where you just didnt bother to put defences, and the game can look totally different.
is there a swift way to smash a 2 base opponent as zerg?
Oh, i hate when zergs just sits on two bases, makes one brillion sunkens and just waits for defilers. Makes offracing less fun. 8[
