Well............I have had three small fills and have a total of 2.8 ccs in a 10cc band so I am not able to provide a perspective based on my personal experience but rather things that I have picked up on this website and from my dr. to be aware of as I work towards restriction. One thing that is important is that if you follow the rules and are not over-filled then you should not experience pain or being uncomfortable when eating. Some people get used to the uncomfortable feeling, vomiting, pbing and it becomes "normal" when it shouldn't be. An overfilled band can be very seducing because with all the vomiting and bringing food back up you might see great weightloss and it is hard to bring yourself to call the dr. with the chance that he/she will take some fluid out of your band and slow the weightloss. In the long run lots of vomiting often can create several problems and you don't want this to happen to you have to fight yourself to let the dr. know what is going on. So that is what I have learned so far- I bet you will get great responses from more experience bandsters. This forum is great but I always conclude with recommending a call to your dr. To answer your question- I don't think a "just right" band would cause you to have to bring up your food and vomit. A "just right" band keeps you feeling satiated and full for several hours after eating a small amount of food. So I am leaning towards either you being "too tight" or really swollen from the recurrent vomiting and pb'ing which I believe might require the same intervention- an unfill.
