Added step 1A to the following:

>> So, you want to do the following:
>>
>> 1: Make sure you properly initialize your inputs as digital as opposed to
>> analog (often controlled by a port called ANSEL, but this varies amoung
>> several different PICs).

1A: You may also have to disable the built-in comparator(s) on some PICs.

>> 2: Make sure your inputs are set up as inputs rather than outputs (this 
>> is
>> the default condition, check out TRIS registers for this).
>>
>> 3: Make sure that interrupts are globally disabled (often a flag bit 
>> called
>> GIE). This is the default condition.
>>
>> 4: Make sure the interrupt-on-change interrupt is enabled (another flag
>> bit).
>>
>> Now a SLEEP should be terminated when the input bit changes, but no
>> interrupt handler is needed.

[notice the mixed "TOP POSTING" and "MIDDLE POSTING", hope nobody flames me 
on this :-)
