How far away from the microphone are you? There is a sweet spot for microphone spacing. Too far away and you sound like you're recording from across the parking lot. To close and you get a whole pile of problems: P-Popping, breath whishes, ticking (my personal favorite), etc. etc., and the sound of someone trying to talk directly into your ear with their lips touching.http://kozco.com/tech/audacity/clips/PPopping.mp3
The Figure-Of-Eight thing is perfectly valid. Older RCA microphones (44BX) naturally work like that and there's no shortage of soap operas produced by preformers clustering around the figure of eight. But that's the key. Unless you're unnaturally close to each other, it may sound gutless and wimpy.
Sweet-Spacing is roughly Hawaiian Shaka.
That's usually too close for people in natural conversation. So if you're recording from opposing sofas with the mic in the middle, you may want to figure a way to get closer.

I'll listen when I get back to the studio.
