Hello, a fill should be one poke into the port and vavoom your done. At least it is with floro. I have a scary story on my first attempt at a fill, but understand my port can not be felt through the skin yet, to much fat I guess. I allowed a fill center to polk me 4 times to the area that they thought the port should be then I worried myself sick for two weeks that the tubing could have been damaged, it wasent but I never want to worrie like that again. Filling since has been a breeze, Ive had three now to reach good restriction. Good luck, vickie
