Didn't work for me but some say it does. It helped me fall asleep but not stay asleep and I always felt like I had a little hangover in the morning.
@Ambassador, did you try the time release kind? I haven't yet, but it's supposed to help you stay asleep. The brand everyone seems to like is Natrol.
@hans01 Glad to hear it helped and that you gave it another try. The first time I tried it I was convinced it spiked my T right after, but I think I was just having bad T anyway and it correlated. The next morning I woke up pretty refreshed and had a low T day.
