Hi Caz, it seems like you need more in your band. Ring and make another appointment with them for as soon as possible. In the mean time you need to find your willpower to prevent putting on any weight.
Easier said than done eh?
Are you eating the right things such as crispbreads / crackers / ryvita to see if you get restriction after eating them or are you eating 'naughty stuff'?
Im dreading getting to your stage (finding ristriction) but ive paid a lot of money for this band to work....and its only me that will stop it, and im not prepared to let it happen.
Good luck hun
