This is my first review for a dose ever on here, and I wanted to make sure it was for this particular gem. This is definitely my favorite simulation I've ever listened to. I never even bother to "condition" myself beforehand, because this one just sucks you right into to the depths of deep pleasure and calm from the start. As you progress further into the dose, it pulls you deeper, and deeper, and soon you feel as though you'll drift into a deep sleep... but suddenly, it shocks you with stimulation, pulling you forcefully, yet pleasurably, back up into consciousness, only to do it all over again. The best aspect of this dose truly is its sheer length. As I lay back and listen, time seems to dilate so much that I think the beats will let me go at any instant, only to be pulled back into a whirlwind of euphoric relaxation. I'm definitely not easy to please when it comes down to binaural beats, but this dose deserves a 5 out of 5.
