Sounds like recurrent Helicobactor Pylori. Need antibiotics.
I have also suffered with the sulfur burps as well but usually after eating fried chicken. I thought it was from poor sanitary conditions of restaurant kitchen but went to other places and still the same. Is it the grease maybe from the fryers causing it? It's odd because fried chicken is my favorite food and have eaten it my whole life it's just recently the burps have started.
I'm probably late to the party but have you tried alka seltzer? I have had bouts of this off and on for about 7 years. I always thought it was eating meat too fast coupled with soft drink and my stomach would stop digesting it but then found out I am lactose intolerant and can't eat overcooked eggs because of the sulphur. I really think it is something to do with a food intolerance. Sometimes I cave though and eat something I am not supposed to (like tonight). Alka seltzer at least helps cut down the duration on the burps and helps get everything moving again. Hope that helps. Even just knowing that I am not a freak and other people are dealing with it too can help me cope.
Do you have candidia overgrowth internal? I have had the burps on and off since childhood. For the candidia growth you have to be very dedicated and follow a certain diet that requires one to give up sugar, carbs, dairy, processed food, anything that turns to sugar and feeds it. I would talk to your Dr. and get tested. You said it started in October which spring and fall produces the humidity to support the growths. My burps are stinking as a result of the toxins being released when they die.I hope this helps and works for you. Peace be with you.
I started having these same exact symptoms every 5-6 weeks starting in Nov 2013. Always started first minute I woke up in the morning. Started with a churning stomach, then when I got up to use the bathroom, I would burp and it would taste like like rotten eggs. Watery feeling in stomach would make me feel nauseated so I would make myself throw up. Pure watery diarrhea. Awful. Lasted over a year. Went to the dr who acted like she didnt care too much, tried to tell her I thought it was Giardiasis, she said probanly not, that Giardiassis wasnt cyclable. I had read it was. She begrudgingly approved a stool test which I knew wasnt going to help because you have to have multiple stool tests to catch parasite. Test came back negative. Mid 2015 started noticing the sickness was getting further and further apart to where I thought it was gone. But this past summer, I statted having episodes again and since late January 2017, I started having the episodes once a week. Cant believe so many people have this same thing.
H Pylori infection? Ask doc to run the test.
