I felt the same way, until my second fill. I don't think I'll go for a third. I do know I need to go for a check up at 3 months. But, I am getting full and staying full, most of the time. I have those days where I feel like I could eat a horse ( and I'm a vegetarian

). But, then there are those days I feel almost too restricted. Most days, It takes about a cup of food to fill me up and to stay full for a few hours. I'm afraid if I go for the scheduled third fill, I'll be to restricted and need to go back for an un-fill.
Don't fret to much about it, you'll get there.
May I ask if you are working out? Working full-time and being a full-time student, I don't have a lot of time. But, I try to do 2 miles I the treadmill 3 times a week.
And remember, the band is supposed to be a slow and healthy weight loss system.
Good luck!
