Well, I went to the office and they did an evaluation. Said my brain waves were good...just showed stiffening of muscles toward the end of the session (which at the time I had sat too long and was ready to move and take my tincture) Still have a lot to think about with this (to try to comprehend it all) They gave me a pamphlet to read and it will take me a couple of days to get to it...(very busy week) ....will try to give you a quick summary when I get the chance to read more about it. Very interesting is my only comment right now
