Im experiencing the same thing. Im still on liquids so I dont know If that makes the difference but I can't tell when Im full. I always feel like I can keep going but I usually stop becuse Im scared and in my mind I know Im doing too much. I never felt any neausea or pain from overeating, but I did feel a little unconfortable after a yogurt smoothie once. I think its because I drank it too fast becuase the feeling went away after a few min.
