Hi iamog!
They way I used them...
I listened to 1A/1B in the afternoon. NBG-A before sleep and NBG-B after breakfast.
It's okay to listen to the B-sides after the A-sides. I would think that it's the best. First on the A-side you get the conscious information and on the B-side you get the paraliminal for your other than concious.
Wishing you the best!
