Result: I've got a tad bit of a headache, my head still feels as if it's "buzzing" too. But I feel extremely calm and well rested. And I slept the entire eight hours. My life has been difficult recently and out of it I developed insomnia. I get very bad anxiety due to work and it keeps me awake. 
Another thing I noticed, my heart and blood pressure have been a bit abnormal lately, (heart rate is 110 on average and BP is 96/50 on average and that's weird for me, my heart is usually 68,BP is usually 118/68) the cause I haven't figured out, however this early morning I woke up and my heart is noy racing as it usually does when I wake up. I don't feel as lightheaded, even though I have a small headache.
I feel calmer, at peace, recently in turmoil I have been the very opposite of peace, having a breakdown once a day. I wake up today feeling. Rather calm, and even happy. 
Usually I watch one of your other videos. Im sure I'm not completely ready for your advanced stuff, but I was desperate to sleep sometime during my weekend off but I return to do back to back 12 hour shifts. 
Im pretty pleased with this result. I hope this helps in your research and experiment. Keep making wonderful videos. :)
Awesome, thanks for sharing!
I'd say it was definitely a workout for your brain -- maybe give it a rest or go back to the beginner track tonight?
