Sky T. reviewed Qualia Night
While this product does wonders for my sleep, the primary reason I use it is because it supports my meditation practice. I live at a monastery, so meditation is my vocation, and I do it every night. If I take Qualia Night an hour prior to the start of my evening sit, the factors of tranquility and equanimity are much stronger. It's surprising just how much it helps. For Meditation nerds like me, this means that Insight/Vipassana practices are a made easier using this product.
Noticeable Trend of Longer Sleep Duration and Higher HRV
Based on Oura ring data, the product didn't seem to have a consistent effect on my levels of REM or deep levels, but it did seem to help me stay asleep longer each night and there was a clear trend of much higher heart rate variability than I'm used to seeing. Overall I feel energized and great.
