I think this was one of the first things I noticed after my surgery that I completely lost the feeling of full. When you are first banded you will not have restriction but you will also not have the feeling of full. I speak at seminars and talk about how the band isn't there to slap you on the wrist it is there to teach you to stop eating when you are satisfied and not "full." Now i do have one question...you are eating small meals but how many times are you eating per day? According to my doctor with the band at a right restriction you should only be eating 3 small meals a day and one 100 calorie snack. The meals shouldn't be larger than a lean cuisine (what my nutritionist says).
As far as bread goes I could eat bread up until my last fill than I began not being able to tolerate it. I could probably physically eat bread very tiny tiny bites very slowly but just because I can doesn't mean I should and considering how narly the PB and sliming feelings are I really avoid them all together. I can no longer do sandwiches or wraps because the carbs ball up before the band. Rice expands so its a definite no no I can do brown rice though.
