I am using both the Sleep Deeply/Wake Refreshed and the Abundant Money paraliminals and despite reading all the associated material, I feel I am using them wrong as they just knock me out and I feel like I have a hangover the next day.

When is the best time to listen to them and how would you listen to them? What is the best way to use them and for how long? I really want them to work before I move on to others.
