    Posted by Reviewer1469541 on Mar 20, 2015

    very happy with how these help me fall fast asleep. I had really bad jet lag and this sorted it out quickly.

    Did not like

    Posted by Reviewer3100355 on Feb 03, 2015

    These did not work for me. I've since learned that I do not like any product with melatonin in it. I now take 5-htp and suntheanine, but separately for their own purposes.

    I probably have the worst insomnia in the entire world!! Tried everything and then discovered Natural Factors Tranquil Sleep formula (lozenges)... I take half of one lozenge and I'm drowsy very quickly. If I take more than half, then the melatonin dose is too much for me and I wake up with a headache. I am over-the-moon with how wonderful these lozenges are. But... I find that with all sleep formula's, it's best to change around every 3-4 days and then they work wonderfully! Now, on to their other formula: Sleep Relax. These are as wonderful as the lozenges, if not better! I just don't know which is better... they both work phenomenally! I just take one and it's plenty... I think two would be too much for me.... suggest you try one first and see how you do.

    Good so far

    Posted by 5744818644961466028 on Dec 28, 2013

    I haven't used many of these yet, but they seem to work nicely. The bottle is very expensive compared to most sleep aids, though it is nice not to have to swallow a huge pill.

    This one is Okay...

    I used to take something else with a red lid...can't remember the name.. Anyway, this one is chewable but works less fast than just the regular tabs. For me, it takes at least 40 minutes to work. But the good thing is that you don't get that dopey feeling in the morning. I think I am going back to the previous one.

    It works as advertised.

    My wife has used this on a few sleepless nights, and it usually works to help put her to sleep. We've found some products that work a little better than this, but it's probably a function of one's own body chemistry.
