These days, I only listen to paraliminals when I absolutely feel the need. This is generally when my mind is racing with self limiting thoughts.

In the past however, I used to listen to one in the morning. If there are 2 parts to a paraliminal (like NBG and NHG) then I would listen to them 30 - 60 minutes apart.

Instant Personal Magnetism is my favourite - and I would listen to it sometime in the day - but no more than 2 paraliminal tapes a day.
