I recently bought a David Pal 36 with CES and I've been using it a lot but it doesn't seem to be having much if any effect on me. I've been doing Alpha and Theta sessions but I don't really feel particularly relaxed during or after the session. Maybe I do a little sometimes, but not enough to say for sure. This must mean that the David is not leading me to generate those brainwaves, or I would feel more relaxed or something different right? In all of the testimonials, and everything I've read, it seems to work for everyone right away. I've tried a lot of the sessions but not all of them - do I just need to find the right session? Or should I be doing something different during the session? Or are there some people it just doesn't really work for? Thank you to anyone who can help me with this.
