I have been using the Memory Supercharger and Personal Genius CDs for 2 weeks and I they have not been helping me. I'm taking classes in math and spanish and I can't remember anything that I am learning. I listen to them during my sleep time stating my purpose before I go to sleep but I have not seen any results. I am getting furstrated because I have tried just about every tape and CD there is and nothing has worked. I am beginning to feel that I can't be helped. What do I need to do that I'm not doing?
