Perfect for low dose, great price
On my second bottle, great product for the cheap price, lasts almost a year. Hard to find in this low dose. I personally find low dose melatonin to work better than the higher amounts. It’s the sweet spot.

Knocks me out cold
I wish I could easily find a lower dose, but this works.
Take one about 30 mins before I want to sleep and when I fall asleep I don't wake up in the middle of the night. I normally have insomnia but one of these generally gives me 9 hours of sleep.
It doesn't ALWAYS work (I have health problems that can keep me awake) but instead of 5-7 hours sleep I am consistently getting around 9.
The only problem is I'm groggy in the morning. But I feel a lot less haggard and anxious in the morning now so I think I'll be continuing with this.

Very good product
These melatonin pills work. I bought them because sometimes I'm so stressed or pressured by everyday life that I find it hard to fall asleep. I don't use them every day, only when I really can't sleep and it's very late. I must say that this pill doesn't knock you out completely. I liked that. You fall asleep slowly, and the next day you don't feel groggy or like you've had too much to drink. It's a great product!
