    Me and my wife both have had major problems with insomnia for the past few years and this is the only supp. we have found that gives us a good night sleep. Phenibut puts you in a good mood about two hours after taking it but it doesnt make me drowsy so I still take melatonin at bedtime. The mel. puts me to sleep but the phen. keeps me in a deep sleep all night. You wake up in a great mood the next morn. and you handle stressful sit. a whole lot better. Only downside to phen. is you can only take it for 3 days, 4 max, then you have to take a 3 day break or it becomes ineffective. I take 7 caps on empty stomach 4 hrs before bedtime.

    For me, this is more about staying asleep than falling asleep. It leaves me a little groggy, but that's WAY better than waking up 2 hours early and being unable to fall back to sleep. And beware of this as being habit forming and hard to stop (ala other internet reports) and use with caution. I use it once a week or less, alternating with other herbs.
