Works Fast! Finally Getting a Great Night's Sleep.
If you struggle with insomnia like Ihave for years, try these, they work incredibly well and have completely fixed my sleep routine! ​I usually take one about 20 to 30 minutes before I want to go to bed, and like clockwork, a gentle relaxation washes over me and I drift right off to sleep. Great fast shipping.. thanks!!

Everyone is different but worked for me!
These work for me! They don't have a taste, pill size isn't too big and definitely a great price for what you get. Puts me to sleep within 30-60 minutes. Everyone is different, but they definitely worked for me!

Smallish pills!
Great way to take melatonin. The pills are small enough so you don't choke and they work pretty fast. I've no idea about the taste, but it doesn't seem to have one. Sometimes I feel groggy in the morning but not overly so. Pretty good product.

Best if you haven't had any real sleep
Works like a charm, I haven't had any real sleep for 13 days and ever since I got this, I finally got the 7 - 10 hour sleep I needed badly. It does make you drowsy and tired and thats what I love about it, this is day 4 of using it and I dont think I'll ever stop lol, the taste is normal like its not bad just bland, easy to swallow lol (thats what she said)
