Hi, I am sorry for the situation you are going through. You are reporting to : - have indigestion problems including low tolerance to meat and sometimes to other food - throw up a slimy, mucus type fluid even if you have not eaten. From what you are saying, it seems that you are having problems with upper GI tract: - gastritis - GERD - or possible ulcer I highly recommend to : - schedule an immediate appointment with GI specialist - and to run further diagnostic examinations: upper endoscopy, abdominal ultrasound For the moment, I advise to: - avoid foods that would cause intolerance - take antacids after meal - eat often and small portions - increase water intake - take probiotics to stabilize intestinal flora Hope it was of help!
