I take it & it has helped me immensely. I use Melatonin with it to help me go to sleep & I only use it at night for sleep. I sleep very well, unless I am flaring with Fibro, because I get such insomnia with the Fibro. I do sleep alot of hours & I allow myself the sleep. I used to try to get up after 8 hours of sleep but with both Fibro & CFS it is a battle of sleepy vs insomnia & groggy vs refreshed. I don't think I could use it if I was working & had to get up.
