Edgard,
It sounds to me like you are trying to get it all out of one activation pass. Remember to limit the activation pass to about 30 minutes. Take a short break and then do another activation pass. However long it used to take you to understand the book see if you can total your activation passes to be about 1/3 the time. EG if it normally takes you 6 hours to regular read and understand then you need to spend 2 hours or 4 x 30 minute activating.
