Had baby and band doesn't seem to work

[mamaof4 0]

I got the band in dec 2006 and did great losing almost 100 lbs in 2 years with a total of 2 cc's in fills. I just had my 4th child in February by c-section and was very excited to get back on track with fills in May. I am now on 2.5 cc's of fill and I barely feel it! I am SO frustrated, continue to feel hungry and eat because of it, therefore gaining weight again in the process!! My PA is doing a limited upper GI in September so I hope to find out more. Anyone experienced this or have any suggestions? My PA makes me wait at least 4 weeks before she will look at filling again. If I can't feel it in the first week or so, I probably am not going to feel it after 4 weeks either. I don't understand why pre-pregnancy I was doing well on 2 cc's and now am beyond that and not feeling anything.

I don't know if this helps or not but the PA at my surgeons office said that after pregnancy the band will most likely work a little different. She said it was most likely because the band location changes slightly and restriction comes with a different amount of fill. She didn't seem to know if I would need more or less fill, we would have to wait and see but fill slowly because it would be different than pregnancy.
