I bought this after considering a few different cortisol management supplements and didn't realize until I received it that this was a product to take at night, to promote sleep but I'm glad I found it! Much like melatonin it reliably helps me get to sleep about 40 mins after I take it, although it seems to provide me with a deeper, longer sleep than 2.5 mg of melatonin- it's almost like taking an ambien in that I sleep through the night and wake up rested, not hung-over.That said, for me it only seems to work really great for occasional use, not nightly. Several times I have taken it a 2nd night in a row and it didn't seem to provide the same benefits after the first night, in that the 2nd night I didn't sleep through the whole night and/or woke up feeling tired or just not rested. I recently tried taking it multiple nights again and I didn't sleep soundly then had weird dreams toward morning- not nightmares, just complicated or difficult dreams, then woke up feeling out of it.Based on my experience, I think this is a great product for when you experience occasional sleep issues. I plan to continue to use as needed, just not frequently.
