Hello. I have recently started taking protein shakes for weight loss and have been having a lump in the throat feeling and excessive mucous in my throat, which hah built up to the point that it is hard to sleep. I have stopped the protein shakes and the throat mucous is becoming less. A couple of years ago I had an anxiety disorder and had as similar feeling in my throat, however, I am no long experiencing anxiety. Is this likely to be due to the high protein shakes?
