insomnia
"This has changed my life. I have long term insomnia with night terrors and a major depressive disorder. 

The first night I slept like the dead, I did find for a couple of weeks that I was tired during the day also, but that has now faded. I still sleep well most nights, and it's natural sleep, I don't feel like I've been drugged. 

My moods have significantly improved too, everything has become more tolerable and easier to handle. My lowest moods are nowhere near as low, and my good moods are better than they've been in years. 

I do find my appetite has increased, but as someone who has struggled all my life to gain weight it's not really an issue."
