They usually ask how ur finding the band if ur eating alot and if u feel any restriction etc etc then they decide how much they give u i dont ask for more than what they decide cos im terrified of a overfill but some people do ask for more i have 5mls at the min so id say i might just get a ml tomorro cos they say from around 5mls its very easy to get a overfill half a ml at this stage can make all the difference and dont worry bout askin questions im glad to help i was asking them myself a few months ago as for the results im thrilled but the past 2wks have been the hardest so far i could eat for ireland before that my wilpower stopped me from eating
