krackrabbit, my mind raced during prologue as well. The CD's were driving me and they were working. I don't recall the goal of the CD's being to trance you out. Rather they are intended to push your nervous system to the point of threshold and to breakthrough to a higher level of functioning.
Yes the first level can be a little uncomfortable but sometimes it is necessary to demonstrate some ruggedness to get through it. Just listen to the CD's for 4 months and don't judge the experience until you get to the end of it. If it was worthwhile then you move on if it wasn't then you send the CD's back. For me the rewards far outweigh any short term discomfort.
