Breastfeeding

I'm breastfeeding at the moment and wondering what I'm going to do when I go back to work. On the whole I"m enjoying breastfeeding even though it has meant changing my diet.

The questions I'm asking myself are
* Will I try and express
* I'm trying to find out as much information about expressing as possible.
* Not sure if I should if i should buy an elletric pump or just stick to my manual pump.
* How will I feel if expressing doesn't work
