Didn't notice any difference
I took this for a couple of weeks. Did not notice a difference in my sleep. I am 59 year old male and sleep Ok, but frequently wake up after 4-5 hours of sleep and then when going back to sleep, frequently don't sleep well after that. This product didn't really help, at all. Nothing negative about it, just didn't even notice, like I hadn't taken it at all. No difference in sleep.
