Further to much that has been said on this thread, I thought I would say that
I was using Holosync last night for the first time this year after a lengthy sabbatical from it.

I decided to use it sitting upright in an arm chair with my back and head reasonably well supported. I felt this would be better than using it lying down which was the way I used to do Holosync. I noticed though that while sitting upright I still fell asleep for much of the session. Nonetheless what I want to ask is whether sitting upright in the way that I have just described is a 'good enough' way to meditate. I guess there may not be a right way, but I feel lying down is certainly not the best method. Any comments or suggestion will be most welcome.

Regards
Steve
