From 2 hours before going to bed you can expect in the order of 8 hours of sleep, so figuring 2+8 you should be awake 10 hours after you bear it.
Really you are supposed to be taking it for 2 days before you expect it to own a solid effect and you will need to pilfer it for 2 days more to get completely put money on on a circadian rhythm
You usually don't feel drowsy after taking melatonin. Just see that you own your normal amount of sleep.
First of adjectives, take it at your bedside, right up to that time you are going to lay down to sleep. Don't take it sooner. And you should allow 6-8 hours for sleep. Everyone is different. Our brains make its own melatonin, but sometimes not enough to grip the sleep cycle. I'm assuming you are experiencing insomnia. After a week or two, you will know the hours of benefit/sleep to expect. Good Luck! And sweet dreams!
