My sleep patterns seem to be getting worse lately. I've been having trouble falling asleep, and have also been having trouble motivating myself to go to bed at a decent hour (probably because I don't feel tired and I know I'll have trouble falling sleep if I go to bed early). Thinking about giving this a try. Does it work? Can you recommend me a good brand? And lastly, it doesn't become addictive like prescription sleeping meds, does it?
