My mother took very strong medicines to sleep, (black stripe), and used them only to sleep, because with age her sleep was damaging. But the "rebound" effect of those medicines did not do her well, in the days after taking the drugs she became so tired and with slow reflexes. Until she met melatonin. From the first day she used melatonin the quality of her sleep was different. It did not increase the amount of sleep but its quality. Not to mention that when she infers melatonin she wakes up willingly, and without problems to get up, without that feeling of wanting to sleep more, because the quality of the night's sleep is extremely satisfying to the body. Already in my case, as I slept very little, (but did not ingest drugs black stripe) helped me even in weight loss because I was overweight. For this reason I recommend melatonin from now foods and highly recommend the site evitamins for being a serious website and that delivers quickly and efficiently.
