Hi there this happened to me as well but i started with 4ml in my band and i think every clinic/hospital is different when i comes to there fill policy the clinic i went to was happy to do my fills earlier than planned for me as i just healed well and was losing weight i was also told that some people put on weight until they hit there "sweet spot" with the band and by this i mean when you feel full on little the amount of food they want you to eat like it could 35Grams or 75grams it all depends again on the clinic/hospital - I was told it could take up to six months plus before the sweet spot is found and everyone again is different when it comes it some people only have 6ml in there band where as i have 7.5 ml in a 10ml band i did have 8ml in but it was too tight for me. People think that having the band as tight as it can go will bring better results but it doesn't it has the opposite effects on you because then nothing is passing those the space the band had made it will get stuck and when food get s stuck its not passing through the nerve in your stomach that controls appetite - the way band has been done for me is it sits just at the top of my stomach i don't have a pouch when food passes through the band it triggers off a nerve there at the top of stomach to send signals to the brain to tell you you are full on little amount of food but you have to eat the right type of food normally it is hard textured food you need to be eating in order to help with band and the body to brake it down slower as well - hope this helps you a little but more.
