I do not have the band, but had a bypass, however I am not sure if I have over eaten as yet, but I get this feeling higher up in my chest of something stuck there and a huge build up of the phlegm like substance.
I think this is over eating, and that is why we need to eat slow as this feeling comes on about 5 min after eating if I eat too quick and maybe too much.
Only had it a few times.
