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.
