Sorry to read about what you are going through. Am not knowledgeable about this and cannot offer help but am interested as an adult family member cannot stand the noise of someone she lives with making noise eating such things as potato chips, crunching, etc. One different may be that the relative eats with mouth open - not sure if because of nasal blockage etc., but am wondering if it is only this particular noise or of others eating softer foods with mouths closed. It doesn't sound as traumatic as the above stories and it must be horrible/frightening to have this ... does your Doctor know and has he/she suggested any possible medication or some sessions with a therapist..... hope get some more comments on here to help you through this to find the cause and cure!
