What is a carb blocker? http://www.wholesalesupplementstore.com/weight-loss-carb-blockers.html Do these work? Anyone ever tried one? They aren't too expensive, thinking about picking up a bottle for cutting on my next protein order. "Manufacturers of carb inhibitors list side effects such as gastrointestinal distress, heartburn, excessive gas and diarrhea." Anyone get severe side effects? .. Thanks--
