I'm always vomiting! After eating 3 spoonfuls of my meal, I always feel there's something stuck then I feel the need to puke so I puke. My doctor said it's very dangerous because the band might move. But I always make sure to eat slowly but the feeling always comes as a surprise. After vomiting, I try to eat again since I feel I haven't eaten at all and I might not get enough nutrients and sometimes I don't puke after. What should I do? Thanks in advance. BTW, I'm 20 years old. :confused:I got banded this May and I have only lost 20lbs.
