I am at six months post op as well and have let myself slide on the rules (eating sweets and French fries and wine!). As a result I have not been losing as much weight. I, like you, can eat anything without getting ill but I still have restriction if I try to eat too much.
As far as hunger goes, I would recommend taking Prevacid. I stopped taking it for a month or so and while I don't have heart burn the Prevacid somehow keeps my hunger on check.
