I never felt full unless it was Thanksgiving or after a trip to Golden Corral! My CDE noticed my boluses were pretty big so she recommended it. Been using it for 4 years and it has allowed me to reduce my insulin, and now I get what it's like to feel full! Lost 12 lbs. soon after also. Great stuff, just make sure to get training on how to take it, because you take that as you star eating, then bolus afterwards.
