i limit myself to half a gram a day (im a serious light weight) and I add tobacco to the shake from the bottom of the bag. I make regular purchases on a regular basis to keep things organized. i buy just enough for one month plus an extra gram or two for the the weekends. i separate my purchase into a pile for myself and to a pile to sell.but sometimes i take an extra eigth from my 'to sell' pile and hide it somewhere (to find later and for emergencies) and raise my price a little.
