Absolutely freaking amazing!
Right from the first night of trying this my sleep changed hugely! Definitely an acquired taste but not so bad when mixed with my favorite sugar free dark hot chocolate. The difference it makes to my sleep is sooooo worth it. Its now been 15 years where my sleep has gone from bad to worse to non existent at times.. this stuff helps me fall asleep faster, sleep calmer and deeper and wake feeling more refreshed that I have in YEARS!! Persist for awhile with it as it might not help straight away, I think I've just been very fortunate (or maybe the sleep deprivation helped)
