best sleep aid I have found
Item Package Quantity: 1, Style: 240 Count (Pack of 1)
this is the best sleep aid I have found. This dissolves under the tongue, goes right into your system and I take two of them every night. They do not work like a sleeping pill and knock you out immediately--- they are natural and take longer plus I feel you need time to get them in your system and feel a difference. Therefore I did not expect immediate results. I have had insomnia for years so I took them for a couple of months when I started noticing the most effect. Now when I take them and let them dissolve under my tongue I know that in about 30 minutes or less I will start to feel drowsy and will naturally go to sleep. Over time I have felt my sleep has deepened and now I rarely awaken during the night. By the way, in the beginning of my search to solve my insomnia problem, I tried taking the melatonin pills that you just swallow but did not get the same results that I have gotten with these that I put under my tongue. Excellent company and excellent product.

WE enjoy falling asleep with these wonderful Melatonin sublingual tablets! Enjoy your Zzzzzzz!
Item Package Quantity: 1, Style: 120 Lozenges Tablets, Item Package Quantity: 1, Style: 120 Lozenges Tablets
Melatonin is produced in humans by the pineal gland. It's a favorite of travelers and helps support restful sleep. We take 1 lozenge at bedtime and let it dissolve. These are great tasting Orange Flavored Lozenges. We only use them at bedtime. And they're just for adults.

Melatonin is useful for sleep in many situations...
Item Package Quantity: 1, Style: 240 Count (Pack of 1)
I have a chronic insomnia problem and I find that melatonin helps. Keep in mind that it will not help if you have something seriously wrong with you such as a chronic pain problem that is keeping you awake. It's not strong enough to overcome that. But it does help with jet lag and it does help with some sleep conditions. You must use it correctly; unfortunately some physicians write that you only need the tiniest dose; others write that you need a higher dose. It is wise to follow a program for sleep hygiene: google "sleep hygiene" and you'll get some good results. I follow ALL of their suggestions and it has helped. The most important thing for me has been to block out light. I leave the lights on low starting at 6 PM. I take the melatonin at 8 PM, some take it earlier. There is no quick-fix for sleep problems but if you keep working at it and you're disciplined, you can find some relief. By the way, if you're not sleeping because of pain and other disturbing symptoms from fibromyalgia (I have it), you need to investigate The Guaifenesin Protocol developed by Dr. R. Paul St. Amand in Marina Del Rey, California. My life was a misery before I found this doctor and started his protocol. I was, in fact, bedridden. I have now regained my life. Source Naturals Melatonin is useful because it does not contain mint (which blocks guaifenesin) and the sublingual form is rapidly absorbed without being destroyed by stomach acid. It is not easy to find but Amazon has it and at the best price.

Simple. Effective. Good value
Item Package Quantity: 1, Style: 240 Count (Pack of 1)
So I prefer chewable that dissolve easily but these are have a slower process. The flavor is mild and pleasing. You can chew them but the texture is more like aspirin I let them melt away and within an hour or so get drowsy. I feel a clean effect from these the dosage 2.5 is good and I dream well with this product that for me is usually the test of how effective it is so A for this one!
