Sleeping on my side with ultrasonics?

[LionKing]

I sleep with my Bose headphones on. I use a sleep hypnosis track to knock me .

I'm pretty sure Shannon has stated it won't have a negative impact on the program. It just makes things "better" if you're getting the full stereo effect.

Isn't not having things "better" a "negative" thing? Anyway, hope it doesn't matter too much for the long-term programs b/c you use them for months anyway.. He does recommend headphones for NSFM (sales page), so maybe its more important for instant effect subs where you only have an hour or two for it to take effect.
