I've already discussed whether melatonin is an effective insomnia cure. Now I have some more information to share with you.
Let's start with the fact that melatonin is not a sleep initiator - it simply regulates your body clock. As I've said before, melatonin is not considered an effective insomnia treatment (although it may help treat circadian rhythm and shift work sleep disorders when a dosage of 0.3-1 mg is taken).
For those popping the melatonin pills, be aware that in pill form, melatonin affects the brain quickly and leaves the body quickly - unlike the body's naturally produced melatonin.
You should also be aware that melatonin doses over over 2-3mg can include side-effects such as nausea, headaches and nightmares. It should never be taken in conjunction with other sleep medications, it shouldn't be used for more than three months, and it should never be given to children.
Doesn't sound like a miracle insomnia cure in reality, does it?
