re: Feeling full verses Feeling in pain

Hi I had my lapbad just on 2 years ago and have lost approx 25 kilo's with still approx 25 to go. Throughout the 2 years I have only had 3 fills (it is a 3 hour trip) for me to get filled as I need to travel to a bigger city to get this done. Anyway whilst I am okay with the 25 kilos I must admit that it has been quite a hard slog and I feel like most of the time I am on a diet and planning what I eat to ensure I dont eat too much which I guess is similar to how I was before banding. My questions are sometimes I feel pain in my arm/jaw and that crushing pain people talk about when they eat too much and then start to gag it back up etc however after that feeling has gone (say 3 minutes) I dont feel full and can just resume eating again. Can someone try and explain what is the "full" feeling I should feel? I have never had a feeling of "OMG, I cant eat another single thing" like I used to in pre band days after eating a big xmas dinner etc. Is the pain feeling the signal to stop and even though I might not have that "full" feeling, am I meant to just stop anyway?? Sorry, there is an awful lot of questions in there but am just confused. Thanks
