I think he is at 5.5cc now. He has already lost 110 pounds and I watch him throw back up about 1/2 the food he eats, but then he gets a fill anyway!!! I'm at 6.25cc, but don't throw up anything unless I try to eat too fast. He still thinks he doesn't have enough restriction, but he can only keep 1/2 of what he eats down...I think his restriction is fine and he should start to exercise!!!
