I began by taking 1g before bed, and over the last 10 days slowly been upping it to the current 3grams. I have never felt 'hit' by a supp like this before. I immediately know when it's working. I feel little tingles all over, followed by feeling extremely comfortable. I fall asleep twice as fast as I used to and sleep much more soundly. Coming from an insomniac who has been prescribed almost every prescription sleep aid on the market, I was very pleasently suprised to find an OTC Supp that could take their place!
