Long time ago I was able to reach what you would call a "meditative" state (what I would call a prayerful state) in which means that your brain moves into producing Theta waves, then Delta waves. I then suffered post traumatic stress disorder and find this state pretty impossible to get to now. Are there any supplements or things I can try to enable my body to once again reach this Theta,Delta state? I think it would greatly help me in my recovery from CFS. I have tried many times but my brain seems just too active. After 40 mins of directed relaxation, I can get down to a relaxed state but nowhere near what I was able to achieve before. Any comments?
