1st fill--???'s

Hi, I am almost 4 months post-op(lap-band) and just had my 1st fill (4cc's) went back next day and had1 1/2cc removed.  Just wondering (3 days post fill) I have been able to eat soup,yogurt, mashed potatoes,cottage cheese, protein shakes, omlett, chicken breast---when I say eat I mean extremely small portions like maybe 3--7 teaspoons then I am full and I eat about 6-7 timesdaily now(chicken was 3 very,very small pieces) and have to stop or littles bits will come back up.  Also before fill was able to take a drink of water no problem now I have to sip at it. Is this normal after fill for what you eat and amount drastically reduced??  Before fill as far as type of food I ate I did not have problems with it going down and staying there was able to eat a wide variety ex--cottage cheese did not bother me now I have to be careful with it .  Thanks for any and all input/ advice
