Restriction?

Now that I've added more foods in. I've been trying to read my body to see if I can feel restriction. My surgeon said I should feel it in my chest, but I haven't felt anything like that. I'll eat my cup of food and still feel hungry. I stop myself so I don't eat more, but I know this won't always happen. My surgeon also said I shouldn't come in for a fill until I stop losing weight, but if the band isn't working the way it should be i.e. causing restriction, shouldn't I go in anyway?
