Hello Paula,
I am from England as well, I live on the South Coast. Try not to get downhearted, sometimes I have wondered if my band is really there! Try and stop and think about what you are doing before you eat. Make sure you sit down to eat with no distractions and eat slowly putting knife and fork down between bites. Sometimes the band only lets you know you have eaten enough if you stop and make yourself aware of it. If you are really hungry between meals try and eat a banana as I find that helps me feel fuller. I have also found that persevering and eating the more difficult foods ensures I eat less and feel fuller. Don't feel like a failure, you aren't, you just need time to adjust. Having weight problems is an emotional rollercoaster and it is normal to have ups and downs. I don't know if any of my advice will help you as we are all so different but don't give up, and don't be hard on yourself
