I had my lap-band put in 7 months ago and now I am having this problem ...?

OK well two weeks ago I had a fill it was my 5th fill and before this I had an unfill well after the 2 days on liquids and stuff when I ate I had the fullness and it felt like my band was tight and at the sweet spot also in this time I take pills in the AM and it is hard to take them but I have to take them and I can't brake them in half well 3 days ago I realized I could take them with no problems and I can eat and I do not feel the same tightness or fullness like before is it that I am just getting used to my band or do I need another fill or is there something wrong I am very confused I called my doc today and they said I just might need another fill and I go back on the 15th but I don't think so has anyone else had this problem?
