    Not so strong

    Posted by bbchris on Jul 26, 2014

    I seem to fall asleep quicky but I don't think the timed release part works or I would stay asleep....

    Takes much longer than advised but gentle enough and no groggy morning feelings

    not so advanced

    This product is okay, but it seems to take quite a while to help me get sleepy and relaxed. I also wake up groggy and very thirsty.

    Worked for the first few hours then I was up

    8 hours Jet lag West to East, staying up all night. Fell asleep for few hours then up all night for the first night with this. Increased to double dose but the same the second day onwards. Gave up and appreciate at least for few hours to be able to sleep. Took 5 days then stopped. Chemical still wins for me.

    Have been taking this for several months - sometimes it seems to work and sometimes it doesn't. Not sure if it's me or the product but will continue to try it.

    Just so-so

    Posted by Reviewer2056917 on Jan 31, 2012

    It makes me sleep within 2 hours after I take it, not speedy one. But, whenever I take it, I have some stomach aching. So, I don't like this melatonin, melatonin at Hyvee is better, I think.

    Takes some time to work

    I have troubles sleeping on school nights. The product requires patience, it takes a few weeks before the effect kicks in. Not the best sleep aid, but at least it's better than pharmaceutical sleep pills.

    Timed release?

    Posted by Reviewer1612446 on Apr 24, 2015

    I bought this with the hope it would help me stay asleep. I don't notice any difference between this and the previous product I was taking.
