Purchased at iHerb

It's been awhile since I've taken the time to write a review, but I had to for this. I ordered this as a freebie to an order and have taken it 2 nights in a row after running out of my melatonin (Source Naturals 2.5 mg peppermint). It's now 4:00 am and I just unloaded the dishwasher! Not helping with sleep whatsoever, in fact it was hard to even fall asleep which I normally don't have a problem with, and I will not be taking these again (I thought maybe last night not sleeping was a fluke and decided to give them a 2nd chance). Can't wait for my melatonin to arrive!!

Did not work

My dad used to take L-Tryptophan years ago to help him fall asleep. I saw it on iHerb and thought I would try it. For me, this product did not work. It did not help me fall asleep. I did not feel any drowsiness. I tried it for several weeks with no results, then discontinued it.
