Well, it's not snake oil. After a single session I just had my first full night's sleep in a long time. Directly following my first 10 minute session, I had a mild headache and slight nausea, so went straight to bed. I slept all through the night, and I never sleep at night. I feel fine now.

My brain is still buzzing, but in a good way. I don't know if this is good, but it's definitely not doing nothing.
