Enough that I get the nods.
Its really quite pleasant, but you should start off with three grams and then work your way up. It is kind of stimulant like at low doses, but I'm a downer kind of guy so a keep eating grams until I start nodding. I also drink when I'm taking it, which enhances the sedative properties. Benadryl (or preferably hydroxazine if you have any), orange or grapefruit juice and just a few beers worth of booze make for a great night on your couch watching the tee vee.
