wow I didn't realize sleep was an 'activity' there.
No, don't put it in. Only count activities that are above and beyond what you listed as your activity level on the main setup. Whatever you select as your activity level will 'assume' a certain level of activity for the whole day. So, going to the gym, cardio, bike rides with the family, sex (yep, its listed) and so forth.
I have no idea why napping is listed, since it consumes no more (and probably fewer) calories than sitting at a desk.
