Had my lap band procedure three years ago and for the past year have maintained a weight number but am not losing. , Problem is I still tend to snack at night and can't seem to break this habit. I'm sure this is my reason for not losing weight. I am 72 years old, active tennis player, don't smoke or drink, not taking any meds, just a lot of vitamins .Need some guidance...Thank you If I don't respond right away it is because I will be traveling to CA. from WA. State, but I will get back with you...
