For Insomnia "I took melatonin 5 mg every other night for three nights. It did help me fall asleep 2 - 3 hours earlier than my normal sleeping time, but it was always a poor quality sleep, very light, tossing and turning in the bed all night long, having weird nightmares and being half-awake. It is close to not sleeping at all. All things considered, I prefer to get some good deep sleep 3 hours later than get 'melatonin sleep' earlier."

For Insomnia "I had horrendous insomnia due to a medication. I would get 2 hrs. of sleep and then be wide-eyed and wide awake. Never even yawned or wanted to sleep. The medication that did this is Guanfacine, an older blood pressure medication. I am on 7 different meds to attempt to get my B/P down near the normal range. This medication works for me but to the detriment of my sleep. I tried everything from over-the-counter sleep meds to Ambien. The last two worked, but I didn't want to become dependent on them. I finally tried melatonin. Even though the research shows that there is no significant difference between placebo and melatonin, I found it to work. It takes a large amt. (12g) and about a week or two, then it begins to work. YES!"

Melatonin for Insomnia "The time-released melatonin gave me nightmares, interrupted sleep, and was less useful than the normal melatonin available over the counter. Woke in the middle of the night with a sore throat and a massive headache. I was on the low dose and couldn't tolerate it!"

Frequently asked questions

For Insomnia "Works very well at first to help you fall asleep, but I sometimes wake up very early or in the middle of the night and can't fall back asleep. But I tend to overthink if I'm just laying in bed trying to sleep, so I'm glad that the melatonin helps me fall asleep quickly. Quite useful for when I have to stay up late doing homework and then wake up early the next day for class. I take it within an hour before I go to sleep, and my eyelids get heavier and heavier from there."

For Insomnia "Made me feel drowsy after taking it, but then after going to bed, it made me have that mixed feeling of drowsiness and insomnia. I had a terrible night using it!"
