Excellent!
It does do a nice job quieting "brain noise" and putting you in a good mood. I expect the effect to build over time, as dopamine/serotonin levels are optimized. This is part of the beauty of Rhodiola vs. Phenibut, which I was also considering. Rhodiola is suitable for daytime use, you don't develop rapid tolerance to it nor is it addictive. Daytime use is important in managing stressful situations because when you lay down at night, it's those stressful episodes during the day that keep the mind racing.
All in all, it addresses the every-increasing stress in today's world. Left unchecked, it's literally a killer. 110,000 million people die annually around the world from it. That's 7 people every 2 seconds!
It's a product who's idea/time has come...
