would quietly listening to binaural beats before, during, or after PR'ing help? if so, should i set it to alpha, or down deeper into theta? I've read in the www.bwgen.com comments (where the presets are) that some ppl have trained themselves to remain conscious while running on deep delta waves. Would being that deep help more than theta (assuming one actually can stay awake at those frequencies)? Any and all comments appreciated.
