I've quit taking prescription sleep aids, thanks to this!
This stuff is THE best! A friend recommended it for my sleep problems, so I got some and have since reordered. It works better for me than melatonin, & I sometimes take both when I am really struggling to sleep. It says it helps with mood, too, & I can't say for certain it's helped with that, because it could just be placebo effect - or actually sleeping decently has improved my mood the next day! - but I suggest trying this if you struggle with falling asleep. I truly have let my prescription, which made me horribly groggy the next day for hours after waking, lapse. This is more economical, less of a hassle, & better for my/your liver. See if it works, & good luck!

Helps my mood
I take it at bedtime and I take several other supplements to sleep. I do believe these help with sleep but I noticed that I am in a better mood most days now. Not something that I had going for me before using this regularly.

Great product for sleep
This is about the sixth refill. I got from this company. They are very good shipping and excellent prices. The packaging was very very good as well.

may cause vertigo
This product is considered a gradual mood elevator as well as a sleep aid. It does help one sleep but , in my case, causes dizziness but does not improve mood . If anything, it causes confusion and vertigo. Too bad , not a feel good experience, for me at least.

Pefect Complement To Your Efforts to Get a Good Night's Sleep
I have been taking 1 tablet 30 - 60 minutes before bed for about a month. Only had three nights where I had trouble falling or staying asleep. I used to have trouble all 30 nights. Anxiety level is down about 90% and morning headaches are nearly non-existent. The L-Tryptophan without Co enzyme B6 did not work nearly as well.

Seems effective for my symptoms, and is a good clean product, no side effects or apparent contamination
I have tried the lowest dose of SRI's available, and still had significant side effects, though they were effective at helping my symptoms, which are being diagnosed as generalized anxiety, something I've had my whole life. When I take nothing, I feel jittery, shaky, irritable, kind of in a state of unrest, like I've had too much caffeine, only all the time. The recommendation on this supplement is up to three times per day, but I notice a difference on only just one. I had no side effects, either, and I feel much mellower. This particular product came as directed, and I had no trouble with it. I also like that it is already paired with its needed coenzyme.

Works better than straight Tryptophan.
I have a sleep problem where I wake up in the early morning hours and feel a bit too tense and awake to go back to sleep. I keep the bottle next to my bed, and when I wake up I take three. Within about 30-45 minutes I feel that tension dissolve and I drift peacefully back to sleep. Without it, I would lie awake for 2-3 hours. I've tried straight Tryptophan, and that worked for me, but when I saw this one, with the added B-6, I decided to try it. My experience is that this stuff is a bit more powerful than just tryptophan. It puts me to sleep a bit quicker, and more deeply.

I take..
... two at night - around 6pm. They don't make me super sleepy, I have to wear myself out. They just make it easier to actually fall asleep, something I previously couldn't do regardless of how tired I was. Usually fall asleep between 10pm - 1am depending on my day, which is good for me. The main reason I take these is to keep my serotonin levels up while I'm taking L-tyrosine. Update: Dropped down to 1 every other night when I started to feel a bit zombie-ish, all is well again. Taking magnesium glycinate is helping me with sleep.
