Yes, but getting the current down is moot because if you look at your logical flow when you get your hardware sorted out the PIC will switch itself off before you get to the STOP point... it's only until then you need a way of stopping you code, thereafter, if everything is working as it should, you'll never get to that point (well in reality you will but the PSU would be in the throws of shutting down anyway).
