Great Product

Posted by Reviewer1847986 on Oct 06, 2009

I am very pleased with this product. Started with 2 tablets as I was using 2 capsules of another brand and found that 1 tablet works just as well. Much easier to swallow than the capsule for me. iherb stands by their shipping policy as they did not send the order the day it was ordered and so upgraded my shipping to a faster delivery.

Ah, sleep...

My doctor recommended this for my anxiety, and it really does help. Without this, I was miserable. Take with juice at bedtime for peaceful sleep.

Helpful in getting off to sleep and waking feeling happier and lighter. Great price and delivery to New Zealand was fast.

Well... My insomnia seemed more powerful than I thought.

I tried two pills per every night to help me fall asleep, but I ended up waking up till 4 or 6 a.m, like I usually did. (I think this symptom of insomnia has slowly developed as chronic one that I could hardly control now.) I could not see any changes, but I will try for three months to see the improvement. If these pills are not working, I might consider to buy more stronger inducer pills. hah...

Brings rest and quiet to the mind to help sleep at night.
