I did try Melatonin from Optimum Nutrition when my mom was having troubles to get sleep, so i bought her a bottle (which is pretty cheap) but i tried it too.
My dose was of 3mg of melatonin nightly 30-60 mins before bed but the firsts days i was feeling nothing from it, just normal sleep. In half of 2nd week i noticed and improve by upping dosage to 6mg (normal dose is 3mg)and i've got a very deep sleep from then. I kept doing 6mg but sometimes i felt so knocked out and tired that it started to get annoying so i returned to 3mg and felt great.
Sleeps from mom and mine were a lot better, my mother got surprised at found Melatonin as an OTC product and at a VERY CHEAP price, so she keeps buying it. From a point of view of deepness of sleep, my vote goes for 6mg dose but the 3mg is quite good, its just that i takes sometime to build up in my body.
Growing up as a cage fighter in a circus, I often found it difficult to sleep. Anticipation of the next fight in addition to squabbles with Skittles, the juggling grizzly bear, plagued my nightly hours worse than the UAW to GM. Fortunately for me, I met a young gypsy, by the name of Drab Tipp, who shared my pains. Drab hooked me up with some new top-secret drug called 'melatonin', and so my story begins...
Side Effects - At 300mcg, some slight drowsiness may be expected upon waking, but nothing too bad. At 3 mg, the drowsiness is bad enough to make you destroy an alarm clock or two.
Sedative - This seems to work moderately well in helping one fall asleep, given a consistent schedule of sleep (circadian rhythm). I never noticed a big difference between the 300mcg and 3 mg doses here. As noted above, the quality of sleep isn't exactly stellar.
Value - It's probably the cheapest sleep aid you can find, really. Fall asleep faster, but lose some quality of sleep. Ahh, compromise is wonderful.
Overall, this product has the potential to aid in sleep, but should be used in limited quantities. I suggest dosing of not much more than 300mcg to avoid excessive drowsiness in the morning. This isn't the miracle pill that many claim it is, in terms of sleep aid - hence why I no longer use it. I consider IBE's Neurobalance to be far superior to this, but it's also far more expensive.
I've found that targeting the source of what ails ye' is a better route, if available. In my case, all I needed to do was slip 2 mcg of H-Drol and 1 mcg of M-Drol into Skittles' wine cooler to send him into instant liver failure. With the circus in dire need of a juggler, I threw down my fighting gloves and pried the famed red juggling balls from Skittles' cold stiff claws. Actually, I still can't sleep worth a damn, but massive quantities of stims still manage to get the job done.
