Mrs Pock,
The more things that you try the more likely you are to find something that works well for you. There are so many different methods and paths that lead to the same place ultimately. You probably got your money back for holosync so, aside from some time wasted, it was at the very least a learning experience.
For the other people that have experienced heavy overwhelm using holosync I would recommend finding a technique like qigong, reiki, yoga, etc to go along with the program. Often we take growth steps that the mind is gungho about but that the body just isn't ready for. Balancing out your Shen using Qigong should dramatically reduce the overwhelm or whatever method you choose. We are not just heads we also have bodies and there is a great deal we can learn from the body.
